Polymer fluids having oxidizable side chains are used on fusing devices in photocopiers to fix particulate thermoplas-tic toner to a substrate while the toner is in a fused state. Typical polymers are the polysiloxanes having oxidizable alkyl side chains, for example, polymethylalkylsiloxane and poly-arylalkysiloxane. Preferred fusing devices are bare metal rolls of iron, copper, aluminum, zinc and the like. The fuser member comprises a solid substrate; a release layer of the polymer fluid which has at least one oxidizable alkyl group per molecule and interacts with the solid substrate, and an interfacial layer which prevents toner from contacting the solid substrate, the interfacial layer being formed by the interaction of the solid substrate and the oxidizable alkyl group of the polymer, fluid.
