PURPOSE:To simplify copying of all kinds of documents, such as thick originals, both side originals, etc., by carrying out 2-step processing consisting of exposure by contact reflection printing and subsequent heating. CONSTITUTION:Color forming material 3 is dispersed into photosensitive resin 4 and this fluid is coated on transparent substrate 2 to form intermediate sheet 1 and photosensitive layer 5. This photosensitive layer 5 face is superposed on original 8 consisting of image part 6 and nonimage part 7, and layer 5 is exposed by illuminating it from the backside of sheet 1 with visible light, ultraviolet ray, or the like. This exposure converts layer 5 of sheet 1 in accordance with image part 6 and nonimage part 7 of original 8, and subsequently, sheet 1 exposed is superposed on image receiving paper 9 and heated to develop the image. This copying system permits simple copying free from discoloration during storage by contact reflection printing. |
