Abstract

A heating device, which can be used in the fixing unit of an image forming apparatus, such as an electrophotographic copying or printing machine, for fixing a toner image on a final substrate. The heating device which is in the form of a heated fuser roller is provided with bands or coatings of material which impede the transfer of heat from the fuser roller to bearing structure associated therewith. The bands or coatings are applied by plasma spraying a ceramic material on either the surface of a fuser roll core or on journals of end caps, depending upon the specific construction of the fuser roller.
