Abstract:
A fixing roller comprising a mandrel and an outermost silicone rubber layer formed of a cured product of an addition-curable liquid silicone rubber composition provided on the outer periphery of said mandrel, said composition comprising:(A) 100 parts by weight of an organopolysiloxane having in one molecule at least two alkenyl groups bonded to silicon atoms; (B) from 1 part by weight to 30 parts by weight of an organopolysiloxane having hydroxyl groups at both terminals of the molecular chain represented by the formula (II): HOâ€”[SiR12O]nâ€”Hâ€ƒâ€ƒ(II) â€ƒwherein each R1 represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 10 carbon atoms, and n is an integer of 18 to 3,000; (C) an organohydrogenpolysiloxane having in one molecule at least two hydrogen atoms bonded to silicon atoms; the hydrogen atoms bonded to silicon atoms in the component (C) being present in an amount of from 0.4 to 5.0 equivalent weight per one alkenyl group in the component (A); (D) a platinum group metal compound in a catalytically effective quantity; and (E) a silica inorganic filler.
