CHARGING MEMBER AND PROCESS FOR PRODUCTION THEREOF, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE

摘要

Provided is an electrophotographic device in which the adhesion of any contamination substance that is accumulated on a cleaning member onto a charging member can be prevented by decreasing the surface free energy and the friction coefficient of the charging member and, therefore, the image failure associated with the adhesion can be improved. A charging member comprising a base, an elastic layer and a surface layer, wherein the surface layer contains a polymeric compound having an Si-O-W bond, and wherein the polymeric compound has a constituent unit represented by formula (1) and a constituent unit represented by formula (2).
