摘要： A heat fixing roll includes a silicone rubber layer on a cylindrical metal mandrel having a penetration of at least 10 according to ASTM D1403 and a fluoroplastic layer thereon. The silicone rubber layer is obtained by molding and curing an addition reaction type liquid silicone rubber composition to the mandrel. The roll provides a sufficient nip width under low pressure, improved abrasion resistance, long-lasting toner release, and a satisfactory fixing function even at a high speed over a long period of time.
