Zusammenfassung:	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.
