ABSTRACT:
A fixing apparatus detects the surface temperature of a heat roller, detects either the temperature of a press roller which press-contacts the heat roller and incorporates a heater, or the temperature of an external heating apparatus which heats the exterior of the heat roller. The fixing apparatus controls the heater of the above-mentioned press roller or the above-mentioned external heating apparatus based on the results of these detections, and thereby performs a high-quality fixing operation without damaging the heat roller.
