Conductive member, charging member using the conductive member, process cartridge using the charging member and image forming apparatus using process cartridge

摘要

An conductive member includes a long conductive supporting body to which a predetermined potential is applied, extending from one side to the other side, an electric resistance adjusting layer, which is formed to surround a circumference surface of the conductive supporting body and adjusts an electric resistance, and a surface protection layer, which is provided to cover a surface of the electric resistance adjusting layer and protects the surface of the electric resistance adjusting layer, and the electric resistance adjusting layer contains a thermoplastic resin material having an ether group in a molecular and an organic phosphonium salt.
