Abstract
An image heating apparatus includes a rotatable image heating member for heating an image on a recording material, a magnetic flux generator for generating magnetic flux for heating the image heating member, an adjustor for adjusting the magnetic flux distribution so that the magnetic flux acting on an end portion region of the image heating member with respect to a rotational axis direction of the image heating member is decreased, a changing portion for changing a sheet passing position of the recording material with respect to the rotational axis direction within a set range, and a switching portion for switching, when the adjustor is actuated and sheets of the recording material are continuously passed, the set range from a range in which the sheet passing position does not overlap with the end portion region to a range in which the sheet passing position overlaps the end portion region.
