Charge transport material that is an ethylene compound, electrophotographic photoreceptor containing the charge transport material, and process for producing the electrophotographic photoreceptor

摘要

A charge transport material having reduced photodeterioration is disclosed to be an ethylene compound having an ethylene double bond site, having a structure in which four different substituents are substituted at the ethylene double bond site, and having general formula (I) below; where R₁, R₂ and R₃ are each independently a hydrogen atom, a halogen atom, an alkyl group of 1 to 6 carbons or an alkoxyl group of 1 to 6 carbons; R₄ is phenyl or tolyl; and Ar is one group selected from the group consisting of naphthyl, biphenyl, anthryl, xylyl, and phenanthryl. An electrophotographic photoreceptor and process for producing the electrophotographic photoreceptor also are disclosed. The electrophotographic photoreceptor includes a conductive substrate; and a photosensitive layer provided on the conductive substrate that includes the charge transport material.
