In the present invention, the driving end support 22 and the waste bin frame 20 are integrally formed, and the step of assembling the driving end support 22 and the waste bin frame 20 is not required in the process of assembling the process cartridge C, so that the photosensitive member 21 can be directly mounted to the waste bin 2.[ Balancing protrusion on waste powder bin ]

When the balance weight 201 is disposed on the conductive end bracket 23 or the driving end bracket 22, the balance weight 201 not only protrudes in a direction perpendicular to the top surface of the waste bin frame, but also extends in a length direction of the photosensitive member 21 or the waste bin frame 20; of course, the weight 201 may be provided on the conductive end bracket 23 and the waste bin frame 20, or on the driving end bracket 22 and the waste bin frame 20, and it is preferable that the weight 201 is integrally formed with at least one of the waste bin frame 20, the conductive end bracket 23 and the driving end bracket 22, regardless of where the weight 201 is provided on the waste bin 2.
[ lubricating Structure of Power receiving device ]

As shown in fig. 3A and 3B, the driving end bracket 22 includes a first through hole 221 formed therein, and the power receiving means 212 passes through the first through hole 221, that is, the power receiving means 212 is supported by the first through hole 221, and when the power receiving means 212 rotates, the power receiving means 212 continuously rubs against the inner wall of the first through hole 221, and in order to prevent the friction deformation of the power receiving means 212 and the first through hole 221 during the whole life of the process cartridge C, the rotation axis of the power receiving means 212 is changed, and the power receiving means 212 and the first through hole 221 need to be continuously lubricated.
In the embodiment of the present invention, the circumferential inner wall of the first through hole 221 is provided with a lubricant accommodating portion, as shown in fig. 3B, where the inner wall of the first through hole 221 includes an adjacent circular arc portion 221a and a non-circular arc portion 221B, the non-circular arc portion 221B is used to accommodate a lubricant, that is, is a lubricant accommodating portion, the circular arc portion 221a is used to support the power receiving device 212, before the photosensitive member 21 is mounted to the waste powder bin 2, the lubricant is applied to the non-circular arc portion 221B, and when the power receiving device 212 receives the rotation of the driving force, the lubricant in the non-circular arc portion 221B can be uniformly applied to other positions of the inner wall of the first through hole 221 and the outer circumferential surface of the power receiving device 212 along with the rotation of the power receiving device 212.

The number of the depressions is at least one, and when the number of the depressions is a plurality, the plurality of depressions may be adjacently disposed or may be spaced apart, and preferably, the plurality of depressions are uniformly disposed along the circumferential direction of the first through hole 221.
[ Structure for mounting Drum shaft pin ]
Fig. 5A is a perspective view of the process cartridge according to the present invention, looking at the waste bin from the conductive end; FIG. 5B is an enlarged schematic view of the conductive terminal portion R2 of FIG. 5A; fig. 6 is a schematic view showing a state in which a drum shaft pin is mounted to a waste bin in a process cartridge according to the present invention.
As described above, the waste bin 2 includes the driving end bracket 22 and the conductive end bracket 23 which are disposed opposite to each other, the photosensitive member 21 is rotatably installed between the driving end bracket 22 and the conductive end bracket 23, the conductive end bracket 23 is fixedly connected with the waste bin frame 20, and the drum shaft pin 213 passes through the conductive end bracket 23 to support the photosensitive drum 211.
As shown in fig. 5A and 5B, the conductive end bracket 23 is provided with a second through hole 231, and as shown in fig. 6, the drum pin 213 passes through the second through hole 231, and in order to ensure that the drum pin 213 is fixed on the second through hole 231, the diameter of the second through hole 231 is generally slightly smaller than the outer diameter of the drum pin 213, so that the drum pin 213 is in interference fit with the second through hole 231.
However, when the process cartridge C including such a waste bin 2 is used at a low temperature, the second through hole 231 is greatly contracted, and thus a phenomenon of cracking occurs, thereby loosening the drum shaft pin 213. In order to prevent the second through hole 231 from cracking at low temperature, as shown in fig. 5B, a first groove 232 is disposed on the circumferential inner wall of the second through hole 231, specifically, the first groove 232 extends radially outwards from the circumferential inner wall of the second through hole 231, and the first groove 232 extends along the penetrating direction of the second through hole 231, preferably, a plurality of first grooves 232 are disposed on the circumferential inner wall of the second through hole 231, and the plurality of first grooves 232 are uniformly disposed along the circumferential square of the second through hole 231, and a protrusion 233 is formed between two adjacent first grooves 232.
Further, in order to prevent the waste bin 2 from shrinking during the injection molding and to achieve more convenient installation of the drum pins 213, the protrusions 233 are provided to have elasticity, and in particular, as shown in fig. 5B, a plurality of second grooves 234 are provided at the outer side of the second through holes 231 in the circumferential direction of the second through holes 231, preferably, the plurality of second grooves 234 are uniformly provided in the circumferential direction of the second through holes, and each of the second grooves 234 corresponds to one protrusion 233, so that a deformable portion 235 is formed between the second groove 234 and the circular arc surface of each protrusion 233, i.e., the circumferential inner wall of the second through hole 231, and when the drum pins 213 are installed, the deformable portion 235 is pressed to be deformed in the radially outward direction of the second through holes 231 as shown by arrow d in fig. 5B, and the drum pins 213 are easily installed into the second through holes 231.
As is apparent from the above description, when the drum shaft pin 213 is installed, the second groove 234 provides a space for the deformable portion 235 to deform, and thus, the second groove 234 is not limited to a specific shape, and the second groove 234 may extend in the penetrating direction of the second through hole 231, may be a through hole or a blind hole, and when the second groove 234 is located in the blind hole, it is preferable that the second groove 234 extends from the longitudinal end of the waste bin 2 toward the waste bin frame 20, i.e., the opening of the second groove 234 is directed to the outside of the waste bin 2.
Further, in order to prevent the deformable portion 235 from being broken due to the too small thickness in the radial direction of the second through hole 231, in the embodiment of the present invention, it is preferable that the distance between the center of the second recess 234 and the center of the circle is greater than the distance between the center of the first recess 232 and the center of the circle in the circle formed by the radial cross section of the second through hole 231. Of course, the first groove 232 may not be provided, but only the second groove 234 may be provided, and the protrusion 233 will not be present, and similarly, the second groove 234 may be provided in the manner described in the above embodiment to achieve easy installation of the drum pin 213.
In the present invention, the manner of conveniently mounting the drum shaft pin 213 is to make the inner wall of the second through hole 231 elastic, and the manner may include providing a plurality of second grooves on the outer side of the second through hole along the circumferential direction of the second through hole as described above, and mounting an elastic member on the inner wall of the second through hole 231, thereby ensuring that the drum shaft pin 213 can be conveniently and stably mounted in the second through hole 231.
As described above, the driving end bracket 22 is integrally formed with the waste bin frame 20, so that the process cartridge C including the waste bin frame 20 is assembled without considering the mounting of the driving end bracket 22 to the waste bin frame 20, thereby greatly reducing the assembly time of the process cartridge C and improving the assembly efficiency.
