摘要：A semiconductive rubber roller used in a printer of a photocopying machine,which is an elongated integral body consisting of a shaft of a metal, a semiconductivefoamed rubber layer on and around the shaft and a semiconductive solid, i.e. non-foamed,
silicone rubber layer on and around the foamed rubber layer. Unexpected improvementscan be obtained in the performance and durability of the roller when the silicone rubberforming the solid silicone rubber layer contains low molecular weight organopolysiloxanemolecules having a degree of polymerization not exceeding 20 in an amount notexceeding 1.0% by weight and by providing the surface of the semiconductive solidsilicone rubber layer with a covering layer which may be a coating layer of a resinouscoating composition or a skin layer having a modified nature by a chemical or physicaltreatment such as ultraviolet irradiation.
