Electrophotographic photosensitive member, an electrophotographic method, electrophotographic apparatus, the electrophotographic apparatus for the process cartridge, long-chain alkyl group-containing bisphenol compounds and polymers using the same

摘要

An electrophotographic photoconductor has an electroconductive support and a photoconductive layer which is formed thereon and contains at least one resin of a polyurethane resin, a polyester resin, or a polycarbonate resin, each resin having at least a structural unit of formula (1): wherein RSUP1/SUP, RSUP2/SUP, RSUP3/SUP, a, b, and n are the same as those specified in the specification. An electrophotographic image forming apparatus and method, and a process cartridge employ the above photoconductor. A long-chain alkyl group containing bisphenol compound is represented by formula (2):
