防止装置。An infrared temperature detection device that has a heating roller having an internal heat source and a pressure roller that is in pressure contact with the circumferential surface of the heating roller, and that detects the temperature of the circumferential surface of the heating roller at a position slightly distant from the circumferential surface of the heating roller. In the fixing device, the fixing device is characterized in that the current supply to the heat source is stopped upon detecting that the rate of increase in the peripheral surface temperature of the heating roller has become smaller than a predetermined temperature increase rate. Abnormal temperature prevention device for equipment.
