Abstract

PURPOSE:To obtain a good 2-color copy stably, by using a specified metal or its oxide at the place in contact with the first photoconductive layer of a conductive substrate, and a carbazole derivative as the charge transfer substance of the first photoconductive layer. CONSTITUTION:A composite electrophotographic receptor contains a second photoconductive layer sensitive to a chromatic light of part of a visible light region, and transmitting the other chromatic light, and a first photoconductive layer sensitive to this transmitted chromatic light. A material consisting of >=1 kinds selected from a group of In2O3, Pd, CrO2, Fe, Ni, Zn, Pb, Au, and Ag is used at the place at least in contact with the first photoconductive layer of the conductive substrate. One or more kinds of bis(dibenzylamino)ethylcarbazole represented by the formula (in which R<1>-R<4> are each H, methyl, ethyl, Cl, Br, or I, and they may be same or different as or from each other) are used as the charge transfer substance of the first photoconductive layer.
