Charging member and apparatus using the same.

摘要

A charging member for use in a contact charging device for charging a charge-receiving member through steps of: applying a voltage to the charging member and disposing the charging member being in contact with the charge-receiving member, comprising: at least an elastic layer and a surface layer disposed thereon contacting the charge-receiving member; wherein the surface layer comprises at least a semiconductive resin and an insulating metal oxide contained in the semiconductive resin. The charging member is usable for constituting a device unit and an electrophotographic apparatus, and is effective for providing an improved withstand voltage and stable image quality. <IMAGE>
