Abstract
An image heating apparatus for heating an image on a recording material. A controller executes a first heater control so that a temperature detected by a second temperature detecting element is maintained at a target temperature of the heater. The controller executes a second heater control for controlling the heater so that a temperature detected by a first temperature detecting element is maintained at a target temperature. When the first heater control is executed, the controller corrects the target temperature of the heater in accordance with the temperature detected by the first temperature detecting element, and when the second heater control is executed, a feeding speed of a recording material in a nip is less than that when the first heater control is executed.
