Abstract
An image heating apparatus including: a heating rotary member, which heats an image on a recording material in a nip portion; an air blowing unit, which blows air toward an air blowing port to cool a predetermined area of the heating rotary member; and a shutter, which opens and closes the air blowing port, wherein a cooling operation can be performed continuously with the shutter opened after image heating processing is completed, whereby a downtime required for making the temperature distribution over the entire heating area uniform after the continuous sheet supply of small-size recording materials is reduced remarkably.
