ABSTRACT:
A silicone composition is formed as a system including a silicone compound, and an unsaturated ester compound having a perfluoro-alkyl group containing 1-20 carbon atoms. The silicone composition is heat-cured to provide a solid silicone rubber composition suitably constituting the surface layer of an elastic revolution body which in turn is suitably used to constitute one or both of a fixing roller and a mating pressure roller in a heat-pressure roller fixing device for electrophotography. In the solid silicone rubber composition, the unsaturated ester compound is stably fixed through reaction with the silicone compound due to the presence of the reactive unsaturation group so that its antistatic effect is retained for a long period.
