Abstract:
1. An image heating apparatus comprising: a heating rotary member, which heats an image on a recording material at a nip portion; air blowing means for blowing air to cool an end portion, in a width direction, of the heating rotary member; temperature detecting means for detecting a temperature of the end portion, in the width direction, of the heating rotary member; and switching means for switching between performing and not performing a cooling operation by the air blowing means prior to a subsequent image heating processing, wherein the switching means performs the cooling operation by the air blowing means in a case where (1) the length, in a width direction, of the recording material to be heated in the subsequent image heating processing is larger than the length, in the width direction, of the recording material having been heated in the previous image heating processing and (2) a detected temperature of the heating rotary member after the previous image heating processing is completed is equal to or higher than a predetermined temperature.
