    摘要: An electrophotographic photosensitive body which has both good image stability and wear resistance under high temperature and high humidity conditions can be obtained by using a novel polycarbonate resin, which contains a structural unit represented by the general formula (I) below and having a long-chain unsaturated hydrocarbon group having a double bond, as a binder resin for a charge transport layer of an electrophotographic photosensitive body. In the formula (I), R1-R4 preferably represent a hydrogen atom or a methyl group, respectively; a represents a number of 7-20; and R6 represents a hydrogen atom, a methyl group or a phenyl group. Particularly preferably, the structural unit represented by the general formula (I) below is derived from 1,1-bis(4-hydroxy-3-methylphenyl)-10-undecene or 1,1-bis(4-hydroxyphenyl)-10-undecene.
