Abstract

PURPOSE: To obtain the title receptor capable of simply performing dichromatic copy without using a filter by using two photoconductive layers having different photosensitive regions in the visible light region and by making the first layer of Se evaporated layer and the second layer of specified double layer.
CONSTITUTION: On electrically conductive substrate 1, the first photoconductive layer 2 made of photoconductive material having sensitivity to colored light transmitted through the second photoconductive layer 3 and layer 3 made of photoconductive material which has sensitivity to partial colored light of the visible light region and transmits other colored light are laminated to obtain a receptor. Layer 2 is made of sensitized or nonsensitized Se evaporated layer, and layer 3 is made of double layer composed of charge generating layer 31 containing disazo pigment and charge transferring layer 32 containing a hydrazone compound.
