When a rotation member stops rotation, driving of a plurality of heating elements is sometimes partially limited. A control unit detects a current flowing to the plurality of heating elements when the rotation member stops rotation, and driving of the plurality of heating elements is partially limited. The control unit sets the power ratio of power to be supplied to the plurality of heating elements during a period in which the rotation member rotates to raise a fixing device to a fixing enable state in accordance with the detection result.
