Abstract:
1. An image heating apparatus which heats an image borne on a recording material by holding tight and conveying the recording material bearing the image at a nip formed between a heating member having a heating element and a pressure member, comprising: a temperature detecting element for detecting a temperature in the vicinity of said heating member; and a control unit for controlling power supply to said heating element so that the temperature in the vicinity of said heating member becomes a target temperature, on the basis of an output from said temperature detecting element, wherein, in a case where, after the recording material of a first width was passed, the recording material of a second width wider than said first width is passed, said control unit sets the target temperature at the time when the recording material of said second width is passed, according to the number of the passed recording materials of said first width and an elapsed time after the recording material of said first width was passed.
