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 havve a sub-micron thickness and therefore present a minimal thermal barrier to the energy being conducted outwardly by the core. The fuser assembly is characterized by the provision of means for controlling the interaction between the core and the material.
