An image heating apparatus includes a first and second heat generating elements, a thyristor that controls electrical power supplied to the heat generating elements, and a relay that switches a supply destination of the electrical power supply between the heat generating elements. A controller switches the thyristor from on to off, and then actuates the relay to switch the supply destination from the first heat generating element to the second heat generating element, and, thereafter switches the thyristor from off to on. The controller sets a timing of switching of the thyristor from on to off to be in a period in which an image on a current recording material is in a nip, and sets timing of switching of the thyristor from off to on to be in a period in which an image on a current recording material or a subsequent recording material is not in the nip.
