提供一种高润滑、难以磨损、难以损坏、长寿命并有助于防止由于覆膜现象和类似原因及上色剂从其上脱除而造成的影像缺陷的光电导体。并改善了用于制造光电导体的涂料液的稳定性。本发明光电导体在其光电导膜或表面保护层中含有聚碳酸酯树脂，所述聚碳酸酯树脂包括含有一种或多种由以下通式(1a)或(1b)表示的结构单元的主链，其中A表示氟原子或氟取代的烷基；和R#+[1]-R#+[7]分别表示氢原子或氟原子。∴ PROBLEM TO BE SOLVED: To obtain the subject by introducing a specific fluorine-contg. group into its main chain so as to give highly durable electrophotographic photoreceptors excellent in lubricity, shaving resistance and scratch resistance, causing no image defects due to filming, etc., and good in toner separation. SOLUTION: This polycarbonate resin is characterized by containing, in the main chain (A) a constituent unit of formula I [A is F or an F-substituted alkyl (pref. of 3-10C); R to R are each H or F] or (B) a constituent unit of formula II (R and R are each same as R ). This resin is obtained by reaction of a polycarbonate compound such as bisphenol A- or Z-type polycarbonate with the corresponding epoxide (e.g. 3-perfluorobutyl-1,2-epoxypropane, 2,2,3,3,3- tetrafluoropropyl glycidyl ether) in the presence of a base catalyst.
