IMPROVED RELEASE OF ELECTRO- Proposed Classification SCOPIC THERMOPLASTIC RESIN TONERS U.S. CL 427/22 FUSED ON BARE METAL FUSER MEMBERS mt. CI. B05d 1/04 Donald A. Seanor

Bare metal fuser members and the method of fusing toner images with bare metal fuser members are well known in the prior art. Generally, bare metal fuser members utilize a reactive release agent which reacts with the surface of the bare metal fuser member to form a thermally stable interfacial barrier layer. Such fuser members and reactive release agents therefor are described in United States Patents 4,011,362, 4,029,827 and 4,101,686.

Typical fuser member materials include anodized aluminum, aluminum, steel, stainless steel, nickel and alloys thereof, nickel plated copper, copper, zinc cadmium brass, tin, lead, platinum, gold, silver, bronze and the like. In accordance with the present disclosure, the bare metal fuser member may be any metal capable of undergoing oxidation and capable of forming a reaction product with a reactive release agent to form a thermally stable interfacial barrier layer on the surface of the fuser member, In accordance with the present disclosure, it has been discovered that prior oxidation of the metal surface results in improved release performance of bare metal fuser members used in conjuction with a reactive release agent. Typical reactive release agents are the carboxy-functional polysiloxanes and mercapto-functional polyorganosiloxanes.

The following examples are given by way of illustration of the instant method for improving release of bare metal fuser members.

                          EXAMPLE I Two similar bare metal fuser rolls were prepared in accordance with the teachings of U.S. Patent 4,101,686. The metal fuser rolls were flame sprayed with a thin layer of iron. One of the flame-sp...
