Image heating apparatus with an air feeding device configured to feed air to a belt cooperating with a heating rotatable member to form a nip for heating an image on recording material

摘要

An image heating apparatus includes a heating roller; a belt forming a heating nip; a heating device for heating the heating roller; a controller for controlling a temperature of the heating roller at temperature depending on thickness of sheet; an air feeding device for feeding air to the be an executing portion capable of executing an operation in a mode in which the air feeding device feeds the air into between the belt and the heating roller while the belt is spaced from the heating roller with the belt and the heating member being rotating. When a thin sheet is fed following a thick sheet, the executing portion executes the operation in the mode after the thick sheet passes through the nip and before the thin sheet is fed into the nip.
