Abstract
A fixing apparatus includes a heating rotator which generates heat with an induced current, an excitation coil arranged outside the heating rotator, a pressure roller which rotates with paper being held between the pressure roller and the heating rotator, the paper having a toner image developed thereon, and a relative position changer which changes a relative position of the excitation coil and the heating rotator to a first relative position when the toner image is being fixed to the paper and to a second relative position when the toner image is not being fixed to the paper. In a cross-section perpendicular to a rotation axis of the heating rotator, a distance from a point in an outer circumferential surface of the heating rotator closest to the pressure roller to the excitation coil is shorter at the second relative position than at the first relative position.
