2. Description of the Related Art Ink jet recording is a method of recording characters or figures on the surface of a recording medium by ejecting ink as small droplets from fine nozzles. Due to the widespread use of inkjet recording devices in recent years, images obtained by such inkjet recording methods, especially color images,
There is a growing demand for high image quality equivalent to that of photographic images, and there is also a demand for less deterioration of its storability.

Therefore, conventionally, the durability of the ink jet recorded matter has been improved by transferring a protective layer onto the surface of a recording medium after ink jet recording.

Water resistance and light resistance of ink jet recorded matter,
As a method for improving the durability including color development and storage stability, a method of transferring a protective layer such as a transparent film to the recorded matter has been proposed. Known transfer methods include a transfer method in which a protective layer is bonded at room temperature and a transfer method in which a protective layer is bonded while heating.

FIGS. 1A to 1C are schematic sectional views showing a conventional transfer method. The transfer sheet 102 shown in FIG. 1A is basically composed of a protective layer 101 transferred onto the surface of a recording medium, and a base material 100 carrying the protective layer. Here, the protective layer 100 can be peeled from the substrate 101 so that it is transferred to the surface of the ink receiving layer 103 of the recording medium 105 after inkjet recording. The recording medium 105 here is composed of the ink receiving layer 103 and the support 104 (see FIG. 1).
See).

In FIG. 1B, the protective layer 101 has a base material 100.
The ink-receiving layer 103 after being ink-jet recorded is covered so as to directly cover the ink-receiving layer 103, and is adhered and transferred onto the ink-jet recorded matter by a treatment such as pressure bonding and / or heating.

Thereafter, as shown in FIG. 1 (c), the base material 100 is peeled off from the protective layer 101 after the protective layer 101 is transferred to the ink jet recorded matter, and the protective layer 101 is formed on the ink jet recording medium 105. Will remain.

In the conventional transfer method as shown in FIG. 1, a transfer sheet 102 having a width wider than that of the ink jet recording medium 105 is usually used.

FIGS. 2A to 2C are partial cross-sectional schematic views for explaining the end treatment of the ink jet recording medium 105 having the protective layer formed by the conventional transfer method.

As shown in FIG. 2A, the inkjet recording medium 105 after inkjet recording on an inkjet receiving layer (not shown) and the transfer sheet 102 provided with the protective layer 101 are aligned with each other and the first roller 201 is provided. It is conveyed between a pair of rollers including the second roller 202.
In a state where the first roller 201 having a heating unit (not shown) is heated, the second roller 202 is pressed,
Inkjet recording medium 1 covered with protective layer 101
It is thermocompression bonded to 05 (see FIG. 2B). that time,
The width of the transfer sheet 102 is the inkjet recording medium 105.
2B, the end portion of the transfer sheet 102 does not exist on the inkjet recording medium during thermocompression bonding as shown in FIG. 2B.

After that, in the step of FIG. 2 (c), the first roller is released after thermocompression bonding, and the base material 100 is peeled off so that the protective layer 101 remains on the ink jet recording medium 105. At this time, a protective layer (hereinafter, referred to as “uncoated protective layer”) 203 that did not cover the inkjet recording medium 203 and an edge portion 204 of the inkjet recording medium are uncovered on the edge of the substrate 100 that has been peeled off. Since the toner adheres to the protective layer and is separated from the recording medium, the end portion is generated as dust 204. It is presumed that this is because the uncovered protective layer comes into contact with the end portion of the inkjet recording medium after recording during thermocompression bonding as shown in FIG. Since the dust 204 adheres to the rollers and the like, it is often necessary to collect the dust.

Further, when the protective layer is provided by the conventional transfer method shown in FIG. 2, printing on the ink jet recording medium must be borderless printing. There may be variations.
