Electrophotographic photoconductor, image forming method and apparatus, and process cartridge using the photoconductor, and long-chain alkyl group containing bisphenol compound and polymer made therefrom

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 R¹, R², R³, 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):
