An image heating apparatus for heating an image formed on a recording material, said apparatus comprising:
- an endless belt;
- a roller contactable with said endless belt to form a nip to nip and feed the recording material;
- a heater provided along a generatrix direction of said endless belt at an inside of said endless belt;
- a guiding member, provided inside said endless belt, configured to guide rotation of said endless belt;
- a reinforcing member, provided between said endless belt and said heater with respect to a radial direction of said heater, configured to reinforce said guiding member, said reinforcing member being provided with an opening to permit radiant light from said heater to reach said endless belt;
- and
- a protecting member, provided between said heater and said reinforcing member with respect to said radial direction so as to oppose said endless belt through said opening, thus suppressing flexure of said endless belt caused by being pressed by the recording material when the recording material is jammed.
