Conductive member, process cartridge using conductive member and image formation apparatus using process cartridge
Abstract:
The present invention provides a conductive member 10 with a superior durability by controlling an electric resistance value of an electric resistance adjusting layer 2 within a semi conductive range, preventing an ion conductive material from bleeding out of the electric resistance adjusting layer 2 to avoid improper charging and avoiding strength decreasing of a weld portion of the electric resistance adjusting layer and an electric resistance value fluctuation. The electric resistance adjusting layer 2 is made from a resin composition prepared by melting and kneading a thermoplastic resin, a high molecular ion conductive material containing an alkali metal salt and a graft copolymer which has an affinity for both the thermoplastic resin and the high molecular ion conductive material.
