ABSTRACT:
A resistance heating element member formed with a resistor member on a polyimide film or resin sheet is fixed to the inner circumferential surface of a roller drum by blow-molding with a heat-resistant resin member. The resistor member includes a metal foil and meanders several times in a predetermined belt-like or serpentine pattern, and electrically contacts slide electrodes arranged on the roller at each side of the roller.
