The present invention provides an image heating apparatus comprising a heater, a film sliding, and a back-up member. The heater includes a first heat-generating member for generating heat by electric power supply thereto, and a second heat-generating member, provided at the downstream side of the first heat-generating member with respect to the moving direction of the recording material, for generating heat by electric power supply thereto, and the first and second heat-generating members are so controlled that the ratio of the amounts of heat generation thereof varies depending on the presence or absence of the recording material in the nip.
