Image heating apparatus and image forming apparatus

An image forming apparatus for forming an image on a recording material, comprising:

• (A) a image forming portion configured to form the image on the recording material;
• (B) a fixing portion configured to fix the image onto the recording material, the fixing portion includes,
• (a) a cylindrical film;
• (b) a heater provided in an inner space of the film, the heater includes a substrate, a plurality of heat generating elements provided on the substrate and aligned in a longitudinal direction of the substrate;
• (c) a roller contacting an outer peripheral surface of the film and forming a nip portion in cooperation with the heater through the film, wherein the image formed on the recording material is heated at the nip portion while the recording material passing through the nip portion;
• (C) an energization control portion configured to control energization to the plurality of heat generating elements so that each of the plurality of the heat generating elements are maintained at a control target temperature in accordance with information of the image;
• and
• (D) an acquisition portion acquires a cumulative amount of heat generation of the heat generating element in each of the plurality of heating areas, and a cumulative rotation time of the pressing member,
• wherein the energization control portion sets the control target temperature of each of the plurality of heat generating elements when controlling energization to the plurality of heat generating elements on the basis of the information acquired by the acquisition portion.
