Abstract
An image heating apparatus includes: an electric energy supplying portion, an endless belt and a heater. The heater includes a substrate, electrode portions including first electrode portions and second electrode portions, a plurality of heat generating portions, and a connecting circuit. The electric energy supplying portion supplies electric energy to the first heat generating portions when a sheet having a predetermined width is heated, and supplies electric energy to the first heat generating portions and the second heat generating portions when a sheet having a width broader than the predetermined width is heated. The connecting circuit includes a single interrupting element configured to interrupt electric energy supply from the electric energy supplying portion to the heater. The interrupting element is provided so as to establish the positional relationship that the interrupting element opposes the first heat generating portions with respect to a longitudinal direction of the substrate.
