Wherein, it should be noted that the reset part C250 in this embodiment can also be the torsion spring part of the second embodiment, and the setting method is consistent with the setting method of the second embodiment, and a free end of the torsion spring part is relatively fixed to the process box 200 A part of it is abutted against, and the other free end is abutted against a part of the control part C242, and the rebound force of the torsion spring part can be used to reset the control part C242.

Embodiment four

This embodiment also provides an electronic imaging device P, specifically as shown in FIG. The motor in the electronic imaging device P receives the rotational power, and transmits the rotational power to the process box 200 to drive the rotation of the rotating elements in it. For other components in the electronic imaging device P, reference may be made to the prior art, which is not described in this embodiment. Let me repeat.

The electronic imaging device P provided in this embodiment, by including the above-mentioned process cartridge 200, realizes the object that the photosensitive element 260 is in contact with the developing element 270 when printing tasks, and the photosensitive element 260 is separated from the developing element 270 when the task is not printed. Therefore, the rubber layer on the outer surface of the developing element 270 is not easily deformed, which improves the printing quality and solves the technical problem that the rubber layer of the developing element 270 in the existing process cartridge 200 is easily deformed due to long-term contact with the rigid element and the printing quality is affected.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the present invention. scope.
