Abstract
An image heating apparatus is provided that enables the entire width of a heat-producing medium to be heated uniformly and an excessive rise in temperature to be prevented, without making the configuration complex. In a fixing unitin which this apparatus is applied, a fixing beltis an annular member that has an inner peripheral surface and an outer peripheral surface, and produces heat through the action of magnetic flux. An exciting coilis located in proximity to the outer peripheral surface of fixing beltand generates magnetic flux that acts upon fixing beltA suppression memberis located in proximity to inner peripheral surface of fixing beltand reduces, of the magnetic flux generated by exciting coilmagnetic flux that acts upon a paper non-passage area of fixing belt
