Claims
- 1. In an electrostatographic toner fusing member having a support and a layer comprising thermally conducting filler particles and a crosslinked fluoroelastomer, the improvement wherein said fluoroelastomer is a crosslinked polyfluorophosphazene elastomer.
- 2. The fusing member of claim 1, wherein said layer forms the outer surface of the fusing member.
- 3. The fusing member of claim 1, having a layer comprising a silicone elastomer between said support and said polyfluorophosphazene elastomer layer.
- 4. The fusing member of claim 1, wherein said support is a cylindrical core.
- 5. The fusing member of claim 1, wherein said polyfluorophosphazene elastomer is a crosslinked polyfluorophosphazene elastomer comprising fluoroalkoxy substituents on the phosphorus atoms that form the polymer backbone.
- 6. The fusing member of claim 1, wherein said filler particles are present in a concentration sufficient to provide a thermal conductivity of at least about 0.5 W/m.degree.C.
- 7. The fusing member of claim 6, wherein the filler particles are aluminum oxide and iron oxide particles.
- 8. In a device for fusing electrostatographic toner to a substrate by applying heat and pressure, said device comprising a first member for pressure contacting and heating said toner and a second member for maintaining said substrate and toner in contact with said first member, the improvement wherein said first member is the fusing member of claim 1.
- 9. The device of claim 8, wherein said first and second members are rolls that form a nip for receiving said substrate.
- 10. The device of claim 8 wherein said filler particles are present in a concentration sufficient to provide a thermal conductivity of at least about 0.5 W/m.degree.C.
