Abstract
An image heating apparatus includes a heating rotatable member for heating, in a nip, an image on a recording material; a heater for heating the image heating member; a cooling device for cooling the image heating member, wherein when a target temperature of the image heating member is changed to a low temperature which is lower than the target temperature, the apparatus is operable in a mode wherein a temperature of the image heating member is lowered by the cooling device to a transition temperature which is lower than the low temperature, and then, the temperature of the image heating member is raised by the heater to the low temperature.
