Abstract
An image heating apparatus for heating a toner image in a nip while conveying a recording material on which the toner image is held is provided. The image heating apparatus includes: a heater configured to generate heat by being supplied with electric power from an AC power source; a rotatable heating member configured to be heated by the heater; a pressing member configured to form the nip in contact to the rotatable heating member; a temperature detecting portion configured to detect a temperature of the heater or the rotatable heating member; and a controller configured to set the electric power supplied to the heater every renewal cycle depending on a detected temperature by the temperature detecting portion. The renewal cycle is shorter in a rise period of the heater than in a period in which the recording material is conveyed in the nip.
