Three color lights, green and blue, were used as light sources for exposure to irradiate the photosensitive dye-containing capsules placed on the sheet. This exposure treatment causes a hardening reaction in the photosensitive outer skin covering the outside of the capsule. In the subsequent process, the dye sealed in the uncured capsules in the unirradiated area is transferred to the special image-receiving paper that is already coated with a color developer that reacts with the dye and reproduces the color. Next, the unexposed capsules are crushed by pressure development. Through this step, the color developer coated on the image-receiving paper and the transferred dye react to develop color and form an image.

In the figure, reference numeral 1 denotes an exposure light source, and a sheet, for example, a photosensitive film 3, is disposed at a portion of the light source 1 to which light 2 is irradiated. The photosensitive film 3 is provided with a capsule containing a photosensitive dye inside and covered with a photosensitive outer skin. This photosensitive film 3 is transferred from one roll 4 to the other roll 4. The photosensitive film 3 is
A pair of pressure rollers 7, 7 together with the image receiving paper 9 during transport.
(first transfer part). This image receiving paper 9 is made of, for example, general PPC paper, is cut out from a paper cassette 19 by a paper feed roller 11, and is conveyed in the direction of arrow A by paper feed rollers 12, 12. A second transfer section is arranged between the paper feed cassette 19 and the pressure effect roller 7, for example a pair of pressure transfers 8, 8 and a film 5 with a color developer 15 and a pair of rolls 6, 6.
It is composed of. The film 5 is constructed by forming, for example, a color developer 15 and a mounting agent 16 on a base film (or base paper) 18 in this order. This film 5
are arranged so as to be held together with the image receiving paper 9 by the pressure transfer rollers 8, 8. Further, a thermal fixing device 10 is arranged downstream of the pressure roller 7 and facing the image receiving paper 9 . Note that this heat fixing device 10 is desirably placed below the image receiving paper 9. Next, the transfer method will be explained. First, exposure light 2 is irradiated from the exposure light source 1 onto the photosensitive film 3 that is fed in the B direction by a pair of rolls 4, 4. As a result, the photosensitive dye-containing capsules 13 arranged on the photosensitive film 3 are selectively cured by a photocuring reaction. On the other hand, the image receiving paper 9 is fed into the apparatus by a paper feed roller 11 from a paper feed cassette 19, and is conveyed in the direction of arrow A by a paper feed roller 12. As shown in FIG. It is transcribed by . Through this process, the image receiving paper 9 containing the color developer is sent to the pressure developing roller (first transfer section) 7. Then, the exposed photosensitive film 3 is combined with the photosensitive film 3, and the unexposed and uncured capsules of the photosensitive dye-containing capsules 13 on the photosensitive film 3 are crushed, and the encapsulated dye 14 is transferred to the receiver paper as shown in FIG. 9 is transferred. The image receiving paper 9 to which the dye 14 has been transferred is sent to a heat fixing device 10 where it undergoes a coloring reaction and fixing process, and is output to the outside of the apparatus.
