Abstract
The present invention relates to an image heating apparatus in which a nip portion is formed by a heating unit, which includes a flexible sleeve and a heater, and a pressure roller. The position of the heating unit is appropriately maintained by pressing the heating unit against the pressure roller using a pressure member so that the heating unit can contact two or more portions of a downstream side rim of a groove arranged on a frame that holds the heating unit, even when the pressure roller is rotated.
