Image heating apparatus and image forming apparatus that control electrical power supply to a plurality of heat generating elements based on a temperature detected by a temperature detecting element

摘要

An image heating apparatus includes a plurality of heat generating elements, a plurality of temperature detecting elements, and an energization controlling portion for selectively controlling, based on the temperature detected by each of the plurality of temperature detecting elements, electrical power to be supplied to the plurality of heat generating elements. The plurality of temperature detecting elements are arranged in each of the plurality of heat generating elements, and the energization controlling portion controls electrical power supply to the plurality of heat generating elements for the purpose of heating a non-sheet-passing heating region, through which a recording material does not pass, among the plurality of heating regions, based on a temperature detected by a temperature detecting element that is farthest from a conveyance reference position of the recording material, among the plurality of temperature detecting elements arranged in the non-sheet-passing heating region.
