Abstract
In an image heating apparatus, a plurality of heat-generating members that a heater has include a first heat-generating member group and a second heat-generating member group, symmetrically laid out with a conveyance reference position of a recording material. A control portion supplies electric power via first and second common circuits to the first heat-generating member group and the second heat-generating member group. A temperature-detecting portion includes a first temperature-detecting element for detecting a temperature of one of the heat-generating members included in the first heat-generating member group, and a second temperature-detecting element for detecting the temperature of one of the heat-generating members included in the second heat-generating member group. The first temperature-detecting element is placed on one side as to the conveyance reference position in the width direction, and the second temperature-detecting element is placed on other side as to the conveyance reference position in the width direction.
