    摘要: The technique of preparing a semiconductive rubber by adding a conductivity imparting agent to resin matrix is so general but controlling the exhibiting conductive properties to a semiconductive range is difficult and in the technique of imparting conductivity by using an electronic conductive agent such as carbon black, uniform dispersion within the system is difficult and this often causes the problems of the sample fluctuation of the electric properties and voltage dependency of the obtained semiconductive rubber. The semiconductive resin composition of the present invention comprises (A) an oxyalkylene polymer having at least one hydrosilylizable alkenyl group in each molecule, (B) a compound having at least two hydrosilyl groups in each molecule, (C) a hydrosilylizing catalyst, and (D) an ionic conductivity imparting agent or (E) a nonionic surfactant. The present invention also provides a semiconductive member having an extremely small fluctuation of resistance due to voltage applied and environment and small change in resistance due to continuous use, which is suitable for electrophotographic devices. The semiconductive member of the present invention comprises a metallic supporting member, a semiconductive elastic layer formed around the exterior of the metallic supporting member and at least one surface layer formed around the exterior of the semiconductive elastic layer, wherein the member has a specific resistance and resistance ratio.
