A heating-fixing device provided with a heating source emitting heat radiation, a roller having the heating source therewithin, a power source for supplying power to the heating source, and a heat-responsive member connected between the heating source and the power source. The heat-responsive member directly senses the heat radiation emitted by the heating source, whereby it quickly responds to the overheating of the heating source. A reflecting member or adiabatic member is disposed on the side of the heat-responsive member opposite the heating source for intercepting the heat which passes by the heat-responsive member.
