Abstract
An image heating apparatus includes: a heater; a supporting member for supporting the heater; and a high heat-conductive sheet sandwiched between a part of the heater and the supporting member. A recording material on which an image is formed is heated by heat from the heater. The supporting member includes a bearing surface contacting the sheet so as to apply pressure between the heater and the sheet and includes an opposing portion opposing a part of the heater not sandwiching the sheet. In a state in which the pressure is applied between the heater and the sheet, the thickness of the sheet is not less than the height of the stepped portion between the bearing portion and the opposing portion.
