<P>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which does not lose electrical properties by crystallization of a charge transport agent and does have sufficient wear resistance when a tetraphenyl benzidine derivative is used as a charge transport agent. <P>SOLUTION: For a photosensitive layer formed on a conductive substrate, a resin which contains polycarbonate copolymer resin represented by the general formula (I) in binder resin, and a charge transport agent which contains as a hole transport agent a tetraphenylbenzidine derivative of a specific structure containing at least two of three kinds of isomers, EE, EZ and ZZ, and 34-65 mass% of EE isomer are used. <P>COPYRIGHT: (C)2012,JPO&INPIT |
