Abstract
An image heating apparatus including: an image heating member, which heats an image on a recording material in a nip portion; an air blower, which blows air toward an air blowing port to cool a predetermined area of the image heating member; and a shutter, which opens and closes the air blowing port, in which the shutter is kept at a closed position when a temperature of the predetermined area of the image heating member is equal to or lower than a predetermined temperature, whereby a temperature rise in a non-sheet passing portion can be efficiently reduced by using the small air blower without lowering the productivity when small-size recording materials are continuously passed nor reducing the lifetime of the air blower.
