Abstract

PURPOSE: To obtain the title receptor capable of simply performing dichromatic color copy without using a filter by using two photoconductive layers having different photosensitive regions in the visible light region and by interposing a middle layer based on light dispersing particles between the first and second layers.
CONSTITUTION: The first photoconductive layer 2 having sensitivity to colored light transmitted through the second photoconductive layer 3 and layer 3 which has sensitivity to partial colored light of the visible light region and transmits other colored light are laminated on electrically conductive substrate 1 to form a receptor. At this time, middle layer 10 is interposed between layers 2, 3. Layer 10 is composed of a light scattering substance such as SiO2, Hansa Yellow, CdS or perylene dye and a binder, and the amount of light dispersing particles used is preferably about 0.01W1wt% to the layer in case of nonphotoconductive patricles and 0.1W 10wt% in case of photoconductive particles.
