ることを特徴とする複写機の定着温度制御装置。A copying machine having a heat roll for fixing transfer paper, a means for controlling the temperature of the heat roll to a set fixing temperature, and a means for detecting that the temperature of the heat roll has fallen to a lower limit temperature capable of fixing. When the heating operation is started by energizing the roll, it is detected that the temperature detected by the temperature detection element that detects the temperature of the heat roll has reached the lower limit temperature for fixing, and copies are made regardless of the actual temperature of the heat roll. A fusing temperature control device for a copying machine, characterized in that it is operable.
