    • PURPOSE:To obtain a receptor with high sensitivity, low residual potential, fatigue resistance and high mechanical strength by using an azo compound selected from specified 16 groups as a charge generating substance and a specified anthracene compound as a charge transferring substance. CONSTITUTION:A laminated photosensitive layer is formed on an electrically conductive support. At this time, the layer is composed of a charge generating layer contg. an azo compound selected from a group represented by formulaI [where X is a ring such as (substituted) benzene, naphthalene or indole, each of Ar1-Ar3 is (substituted) benzene, naphthalnene or heterocyclic, each of R1 and R3 is H, (substituted) alkyl or phenyl, R2 is (substituted) alkyl, carboxyl, phenyl or the like, and R is H or (substituted) alkyl]and other 15 groups each having radical A and of a charge transferring layer contg. a compound represented by formula II[where X is H or halogen, and R is a (substituted) aromatic ring]. Thus, a receptor with high mechanical strength and superior photosensitive characteristics is obtd.
