Abstract:
An image heating apparatus includes a heater having a plurality of heating elements arranged in a direction orthogonal to a conveying direction of a recording material, each of the plurality of heating elements having a heating region, and a control portion that controls electrical power to be supplied to the plurality of heating elements, the control portion being capable of individually controlling the plurality of heating elements. The control portion executes control of a heat generating quantity of each of the plurality of heating elements such that a heat generating quantity when heating a first region of the recording material including an image, a heat generating quantity when heating a second region of the recording material not including an image, and a heat generating quantity when heating a third region, in which there is no recording material, are different from each other.
