    • 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.
    • 通过使用含有下述通式(I)所示的结构单元并具有长链的新型聚碳酸酯树脂,可以获得在高温高湿条件下具有良好的图像稳定性和耐磨性的电​​子照相感光体 具有双键的不饱和烃基,作为电子照相感光体的电荷输送层的粘合剂树脂。 在式(I)中,R 1 -R 4优选分别表示氢原子或甲基; a代表7-20的数量; R6表示氢原子,甲基或苯基。 特别优选由下述通式(I)表示的结构单元衍生自1,1-双(4-羟基-3-甲基苯基)-10-十一碳烯或1,1-双(4-羟基苯基) 十一碳烯
