PROBLEM TO BE SOLVED: To provide a conductive roller having excellent triboelectric characteristics, carrying property of toner and wear resistance. SOLUTION: This conductive roller for electrophotographic device consists of a cylindrical core metal and a roller member concentrically layered around the core metal. The roller member consists of a polyurethane elastomer produced by the reaction of a polyol component and an isocyanate component. The polyol component contains a polysiloxane having active hydrogen on both molecular ends, and is preferably a dimethylpolysiloxane. |
