ABSTRACT:
A contact fuser assembly for use in an electrostatic reproducing apparatus including an internally heated fuser roll structure comprising a rigid or non-deformable, thermally conductive core capable of interacting with a material applied thereto in such a manner as to form a thermally-stable interfacial coating intermediate the surface of the core and a release coating also formed thereon. The interfacial coating strongly adheres to the core surface and prevents toner material from contacting the outer surface of the core. The combined coatings have a sub-micron thickness and therefore present a minimal thermal barrier to the energy being conducted outwardly by the core. The interfacial coating is provided by a thermally degradable substance with polyethylene and the release coating comprises a low viscosity silicone oil.
