Abstract

PURPOSE: To obtain the title receptor capable of performing dichromatic color copy in a single exposure process by using two photoconductive layers having different photosensitive regions in the visible light region and by making the first and second layers of specified double layers, respectively.
CONSTITUTION: On electrically conductive substrate 11 first photoconductive layer 12 composed of eutectic layer 121 consisting of a pyrylium type dye and an electrically insulating resin and charge transferring layer 122, and second photoconductive layer 14 composed of Se layer 141 made of Se material such as Se-As alloy having little and color sensitivity and charge transferring layer 142 are laminated to obtain a receptor. Upper layer 14 of this receptor has sensitivity to partial colored light (non-red light) of the visible light region and transmits other colored light (red light). On the other hand, lower layer 12 has sensitivity to red light.
