An image heating apparatus comprising:
- a heater which is stationary in use;
- a film slidable on said heater;
- a backup member cooperable with said heater to form a nip, with said film being interposed between said backup member and said heater, wherein an image carried on a recording material is heated through said film while in the nip by heat from said heater;
- and
- feeding interval controlling means for varying the recording material interval, wherein said control means expands the feeding interval each time the consecutive feeding of the recording material reaches a predetermined number as the recording materials are being consecutively fed.
