PURPOSE: To obtain a photoconductive film sensitive body high in sensitivity and low in residual potential and an electrophotographic sensitive body good in durability b incorporating at least one of styryl compounds specified in structure as an electric charge transfer material, and at least one of bisazo pigments specified in structure as a charge generating material. n CONSTITUTION: A charge transfer layer 3 formed on a charge generating layer 2 contains at least one of the styryl compounds represented by formulae I and II in which each of Ar 1 WAr 4 is optionally substituted aryl, and n is 0 or 1. A charge generating layer formed between a conductive substrate 1 and the charge transfer layer 3 contains at least one of the bisazo pigments represented by formula III in which each of R 1 and R 2 is H, lower alkyl, aryl, or the like; Z is an atomic group necessary to condense with the pyrazine ring to form an optionally substituted aromatic hydrocarbon ring or hetero ring; A is a group of formula IV; X is an atomic group necessary to condense with the benzene ring to form an optionally substituted aromatic hydrocarbon ring or hetero ring; Y is a group of formula V; and R is H or the like. n COPYRIGHT: (C)1989,JPO&Japio |
