ABSTRACT:
A silicone composition is formed as a system including: a silicone compound, reactive group-containing modified silicic acid powder of which surface has been modified with an alkylsilane, a hexamethyldisilazane, a dimethylsilicone oil, or a mixture thereof, and an unsaturated group-containing silane compound; and inorganic fine powder carrying a surfactant. The silicone compound is preferably an addition reaction-type silicone rubber prepared from a dimethyl polysiloxane having a vinyl group, a methylhydrogenpolysiloxane and a platinum-based catalyst. The silicone composition is heat-cured to provide an elastic revolution body which is suitably used to constitute one or both of a fixing roller and a mating pressure roller in a roller fixing device for electrophotography.
