To prevent the cracks of a conductive adhesive layer for bonding a power receiving member and the inner surface of a fixing roller, which is elastically deformed when it is pressed by a pressure roller, when using the fixing roller which is made small in thickness in order to shorten a rising time from starting power supply to a fixing device until the fixing roller attains a prescribed fixing temperature.

This inner surface heating type fixing roller 1 is provided with a cylindrical base substance 1B and a heating resistor layer 1D formed on the inner surface of the base substance 1B via an insulating layer 1C and energized to generate heat. Power receiving members 14A, (14B) attached and fixed on the layer 1D of the roller 1 are formed of a thin conductive material which can be elastically deformed, electrically connected, and fixed on the layer 1D by the conductive adhesive layer 12A, (12B).
