Abstract
PURPOSE:To obtain a photoreceptor high in sensitivity and not deteriorating characteristics even when charging and exposing are repeated for a long term, by adding >=1 kinds of specified 3 kinds of hydrazone compounds to a charge transfer layer, and >=1 kinds of specified bisazo compounds to a charge generating layer. CONSTITUTION:A charge transfer layer contains a hydrazone compound represented by the formulaeI, II, and III in which R11, R12, R14, R15, R21, R22, R23, R24, R32, R33 are each optionally substituted alkyl or aryl; R11 and R12, R23 and R24, R32 and R33 each may combine with each other to complete a nitrogen- containing hetero ring; R13, R16, R25, R26 are H, halogen, or optionally substituted alkyl or alkoxy or aryloxy, or the like; R17, R31 are H or optionally substituted alkyl or aryl; R27 is a divalent residue; A is optionally substituted heterocyclic; and n1, n2, n3 are each 0 or 1. A charge generating layer contains a bisazo compound represented by the formula IV in which A1, A2 are each a coupler residue; R41, R42 are each a divalent organic residue; and R43, R44 are H, optionally substituted alkyl or aryl. Accordingly, a photoreceptor superior in durability can be obtained.
