Abstract: PURPOSE:To copy a lot of color original in a short time by forming an image on a transparent developing sheet with the aid of a micro-capsule sheet, forming an image on a prescribed developing sheet using the said sheet as an original plate, and printing this developing sheet. CONSTITUTION:The micro-capsule sheet 11 is irradiated with an image light corresponding to the image of an original to be copied from a cathod ray tube 13. After a latent image is formed on the surface of the said sheet, the irradiated part of the micro-capsule sheet 11 is carried to pressing rollers 15a and 15b. At this time, the transparent developing sheet 14 is carried to pressing rollers 15a and 15, and press-contacted with the micro-capsule sheet 11. As a result, the latent image formed on the micro-capsule sheet 11 is transferred onto the developing sheet 14 and a color image which is the same as the original is reproduced on the transparent developing sheet 14. Images are continuously copied on developing sheets 24 by using the developing sheet 14 as the original plate. Thus, a large number of color originals can be copied in a short time.
