ELECTROPHOTOGRAPHIC MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

摘要

The present invention provides an electrophotographic electro-conductive member containing an ion-exchange group structure in an electro-conductive layer, whereby the bleeding of an ionic conductive agent to the surface of the electro-conductive layer is suppressed and reduction in electro-conductivity caused by electrification is low. For this purpose, the electrophotographic member of the present invention is an electrophotographic member having an electro-conductive mandrel and an electro-conductive layer, wherein the electro-conductive layer contains a resin having any one or more of partial structures represented by the specific formulas (1) to (7) in the molecule, and an anion.
