Abstract: PURPOSE: To restrain the temperature of the non-paper-passing part of a roller from rising with a simple constitution so as to prevent hot offset, abnormal image formation, and the local deterioration of a device by providing a heat radiating member brought into contact with the internal peripheral surface of a hollow roller and radiating the heat of the part. CONSTITUTION: The surface temperature of the roller 1A is detected by a temperature sensor 4 at an area which does not contribute to the heating of a recording paper in the shaft direction of the roller 1A. Next, when the surface temperature of the area reaches a specified temperature, the sensor 4 sets the condition of an attaching/detaching mechanism so that the heat radiating member 2 is brought into contact with the internal peripheral surface of the roller 1A. Thus, the member 2 is brought into contact with the area which does not contribute to the heating of the recording paper in the shaft direction of the roller 1A, absorbs the heat at the area, and radiates the heat.  The attaching/detaching operation of the member 2 is performed in accordance with the temperature detection of the sensor 4, so that temperature falling by means of heat transmission from the heated area in the shaft direction of the roller 1A caused when the member 2 is always brought into contact with the area is prevented.
