An image heating apparatus has a heater, a film for transferring heat from the heater to an image on a recording material, a rotary backup member for forming a nip with the film and a cleaning member for cleaning a peripheral surface of the rotary backup member. A device for moving the cleaning member is provided so that the cleaning member comes in contact with, or moves away from, the surface of the rotary backup member such that the moving device places the cleaning member in contact with the surface of the rotary backup member after the temperature of the rotary backup member increases.
