ABSTRACT:
Toner images are fused to a substrate, such as paper, with a heated fusing member having a silicone elastomer fusing surface by coating the elastomer fusing surface with a toner release agent which includes an unblended polydimethyl siloxane having a kinematic viscosity of from about 7,000 centistokes to about 20,000 centistokes. In a preferred embodiment the polydimethyl siloxane oil has a kinematic viscosity of from about 10,000 to about 16,000 centistokes and the fuser member is a fuser roll having a thin layer of a crosslinked product of a mixture of .alpha..omega.-dihydroxypolydimethyl siloxane, finely divided tabular alumina and finely divided iron oxide.
