Abstract
An image heating apparatus includes an image heating rotational member configured to heat an image on a recording material, a pressure member configured to form a nip portion with the image heating rotational member and pinch the heated recording material in the nip portion, a first external heater including a first heat generation member and configured to contact an outer surface of the image heating rotational member and heat an area of the image heating rotational member that has passed the nip portion, and a second external heater including a second heat generation member and configured to contact an outer surface of the image heating rotational member and heat an area of the image heating rotational member heated by the first external heater. In the image heating apparatus, maximum power applied to the second heat generation member is smaller than maximum power applied to the first heat generation member.
