PROBLEM TO BE SOLVED: To provide an electrostatic charging member provided with a resistance layer being free from the occurrence of an image defect as a result of resistance unevenness, and an electrophotographic device forming a uniform and faithful image being free from unevenness, even adopting thermoplastic resin or elastomer for a resistance layer of an electrostatic charging member. SOLUTION: In the electrostatic charging member consisting by laminating in an order of a conductive elastic layer the resistance layer on a conductive support, this electrophotographic image forming device is provided with the resistance layers, composed by the resin composition composed of (A) at least, at one hand of terminal of ethylene-butylene copolymer, the copolymer resin composed by bonding block polymer selected from a group consisting of styrene block polymer and olefin block polymer, (B) polyolefin resin of average molecular weight beyond 10,000, (C) the polyolefin resin of average molecular weight below 10,000, and provided with these charging member.
