(57) [Summary] [Object] It is an object of the present invention to provide a charging member, a transfer member, and a cleaning member, which change little even after long-term use. [Structure] A base material containing an ionic conductive material and a rubber layer provided on the surface of the base material. The rubber layer is mainly chlorinated polyethylene, chlorosulfonated polyethylene, ethylene-propylene-diene terpolymer. Alternatively, a charging, transfer and cleaning member comprising 1,2-polybutadiene, wherein the rubber layer further contains a conductive material. Furthermore, it is a member characterized in that the rubber layer contains silica. |
