PURPOSE:To obtain the copies of all the documents such as thick originals and both-sided originals as clear developed color images by carrying out exposure by contact reflection and development using a heating means. CONSTITUTION:Photosensitive layer 5-1 corresponding to the dark portion of original 9 undergoes no remarkable change when exposed, since the irradiated light is absorbed in the dark portion. On the other hand, since the light is reflected from light portion 8 of original 9, in photosensitive layer 5-2 corresponding to portion 8 resin 4 is set. Simultaneously photosensitive coloring component A3 is exposed and undergoes a change. After the exposure cover film 6 is peeled off from middle sheet 1, and sheet 1 is superposed on image receiving paper 10 and heated to soften resin portion 5-1, whereby component A3 contained in portion 5-1 melts, diffuses, and reaches the surface of coloring component B-layer 12 of paper 10. Accordingly, the component A reacts with the component B, forming developed color image 13 on paper 10. |
