To reduce a thermal load for a heating belt, when an image is fixed to a medium whose width is smaller than that of the heating belt by the heating belt.
When the control part of an image forming apparatus determines that a paper used for an instructed image formation is a maximum width paper, the control part stops the end sensor of a measurement part and the resistance heating element of an auxiliary part. Then, the control part reads temperature measured by a central sensor and controls high-frequency power supplied to the exciting coil of an electromagnetic induction part, according to the read temperature. On the other hand, when the control part determines that the paper used for the image formation is not the maximum width paper, the control part reads the temperature measured by the central sensor and controls power supplied to the resistance heating element of the auxiliary part, according to the read temperature. Then, the control part reads the temperature measured by the end sensor and controls the high-frequency power supplied to the exciting coil of the electromagnetic induction part, according to the read temperature.
