Abstract
An image heating apparatus includes a first rotatable member and a second rotatable member which are configured to form a nip in which a toner image is fixed on a recording material; an air blowing mechanism; a duct configured to guide air from the air blowing mechanism toward an end portion of the first rotatable member with respect to a longitudinal direction of the first rotatable member; and an opening and closing mechanism configured to open and close an air blowing port of the duct. The opening and closing mechanism includes a plurality of shutter members configured to close the air blowing port in cooperation with each other.
