PURPOSE:To improve the visibility of a copy by transmitting reflected light from an original respectively through plural filters, forming light transmitting films each of which forms a light non-transmitting part and a light transmitting part and radiating beams to the surface of photosensitive paper coated with prescribed color developing materials to expose the paper through the films. CONSTITUTION:Red, green and blue filters 8-10 are successively set up and reflected light beams from a color original 1 are individually transmitted through the filters 8-10 to form an electrostatic latent image on a photosensitive body 6, and the latent image is developed by a toner developing device 13 and the developed image is transferred to the surface of an ultraviolet transmitting film 14. When the film 14 is advanced, a black toner transfer position based upon red filter 8 is superposed to photosensitive paper P and ultraviolet rays are projected from an ultraviolet light source 19 through a cyanine interference filter 21, the ultraviolet rays are passed through the part having no toner adhesion and reacted only with a cyanine developing material on the paper P by photocuring. When the paper P is returned to the original position and exposure processing of magenta and yellow, respective reference colors in the primary colors, exposure processing is executed similarly to cyan processing, optically uncured color developing materials are developed and fixed by a heat fixing roll 25.
