PROBLEM TO BE SOLVED: To provide a silicone rubber sponge forming composition for a fixing roller, which can be made as a cured product forming a fine and uniform cell, having low thermal conductivity, and superior in durability, and to provide the fixing roller, made of the same, having the low thermal conductivity, and superior in the durability. SOLUTION: The silicone rubber sponge forming composition for the fixing roller contains (A) 100 pts.mass of a liquid organopolysiloxane including at least two alkenyl groups combined with silicon atoms in one molecule, (B) 0.1-30 pts.mass of a liquid organohydrogenpolysiloxane including at least two hydrogen atoms combined with silicon atoms in one molecule, (C) 1-20 pts.mass of a surfactant, (D) catalytic amount of an addition reaction catalyst, (E) 0-10 pts.mass of reinforcing silica fine powder, and (F) 30-200 pts.mass of water. The fixing roller formed using the composition and the method for manufacturing the same are provided. COPYRIGHT: (C)2005,JPO&NCIPI
