Abstract:
A fluorocarbon resin-covered fixing roll comprising a shaft having cured thereon a silicone rubber layer comprising the reaction product of a liquid silicone rubber composition comprising(A) 100 parts by weight of a diorganopolysiloxane which has at least two silicon-bonded alkenyl groups in each molecule and is liquid at room temperature, (B) 5Ëœ300 parts by weight of an inorganic filler, (C) an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms in each molecule in a quantity that affords a value of from 0.3:1 to 5:1 for the ratio of the number of moles of silicon-bonded hydrogen atoms in the present component and silicon-bonded alkenyl groups in component (A), (D) a platinum catalyst in a quantity that affords a value of from 0.1 part by weight to 500 parts by weight of platinum metal atoms per 1,000,000 parts by weight of component (A), and (E) 0.01Ëœ10 parts by weight of a particulate hydroxide or oxide of an alkali metal, or a particulate hydroxide or oxide of an alkaline earth metal; and a fluorocarbon resin layer on the peripheral surface of the silicone rubber layer.
