Abstract
An image heating apparatus including: an image heating member for heating an image formed on a sheet at a nip portion; a temperature detector for detecting temperature of a predetermined region of the image heating member; a cooler for cooling the predetermined region; and an activating device for activating the cooler to perform a cooling operation in accordance with an output of the temperature detector, wherein the apparatus has a first mode of stopping a cooling operation in accordance with an output of the temperature detector; and a second mode of stopping the cooling operation in accordance with an end of image heating processing irrespective of the output of the temperature detecting device. The image heating apparatus is capable of suppressing unnecessary energy consumption, and of eliminating uneven glossiness due to a reduced temperature region at a boundary between a sheet passing portion and a non-sheet passing portion.
