Abstract:
An energization controlling portion selectively controls energization of a plurality of heat generating elements so that electric power to be supplied to the heat generating elements to heat a non-image heating region, through which an image formed on a recording material does not pass, among a plurality of heating regions of an image heating portion, is smaller than electric power to be supplied to the heat generating elements to heat an image heating region, through which the image passes, among the plurality of heating regions. When an abnormality detecting portion detects an abnormality in an image forming apparatus, the energization controlling portion increases the electric power to be supplied to the heat generating elements to heat the non-image heating region.
