ABSTRACT:
A heating roller device including a center shaft, a heat roller rotatably supported on the center shaft, and heating means provided inside the heat roller has the wear resistance of the outer surface of its heat roller outer surface increased and its availability factor enhanced by forming the outer surface of the heat roller with a hard carbon film of hydrogenated amorphous carbon. The hard carbon film is preferably formed on an intermediate layer formed on the outer surface of the heat roller beforehand so and to increase its adhesion to the outer surface. Wear resistance can be further enhanced by forming the outer surface of the heat roller with a hard layer, forming an intermediate layer on the hard layer and forming the hard carbon film on the intermediate layer.
