A fixing device which makes it possible to reduce power consumption during a non-fixing operation while reducing the time before fixing is started. A belt has a conductive layer provided thereon. A pressure roller is rotated in a state engaged with the belt to thereby cause the belt to be rotated in a driven manner. Exciting circuits each formed by a magnetic core and an exciting coil generate an eddy current in the conductive layer provided on the belt to thereby cause heat to be generated in the conductive layer. A plurality of the exciting circuits are arranged at different locations along a rotational direction of the belt, and a controller drivingly controls the exciting circuits in respective timings in a state where the belt and the pressure roller are disengaged from each other. |
