ABSTRACT:
An image heating apparatus includes a first image heating device for heating a toner image on a recording material. A first temperature detector is provided for detecting a temperature of the first image heating device. A second image heating device is also provided for heating the toner image on the recording material heated by the first image heating device, and a second temperature detecting device is provided for detecting a temperature of the second image heating device. Still further, a controller is provided for changing a number of recording materials passing through the first image heating device and the second image heating device per unit time on the basis of the detected temperature by the first image heating device and a detected temperature by the second image heating device.
