PURPOSE:To stably execute favorable 2-color copying, by using an interlayer composed of a specified multilayered structure in a composite electrophotographic receptor consisting of 2 kinds of photoconductive layers laminated sandwiching said interlayer. CONSTITUTION:A first photoconductive layer 12 sensitive to a chromatic light transmitted by a second photoconductive layer 14; an interlayer 13; and the second photoconductive layer 14 sensitive to part of the chromatic color and transmitting the test of it are laminated in order on a conductive substrate 1 to form a composite electrophotographic receptor. Said interlayer 13 consists of a 2-layer structure of an upper layer 132 and a lower layer 131. This lower layer 131 located on the layer 12 contains an electron acceptor, such as maleic anhydride or an electron donor, such as hexamethylenediamine. When the interlayer 13 composed of 3 layers, said compound is added to the middle layer. |
