Abstract

A thermal conductive roller (10) for use in copying machines, steam-heated and induction-heated application includes a ceramic heating layer (14) formed by plasma spraying a ceramic material to form an electrically conductive heating layer of preselected and controlled resistance. Several methods of controlling the resistance of the ceramic heating layer (14) are disclosed. The ceramic heating layer (14) is sealed with a solid, low viscosity sealer (24) such as Carnauba wax to protect the ceramic layer from moisture penetration. Electrical current is applied at or near the core (11) and is conducted radially outward through the heating layer (14) to an outer grounded metallic layer. An outer contact layer (16) of metal, ceramic, or polymeric material can be added.
