Abstract
An image heating apparatus includes: a heating member configured to heat a toner image formed on a sheet by using a toner containing a wax; an exciting coil; a magnetic flux suppressing member configured to suppress a part of magnetic flux actable from the exciting coil onto the heating member; a screw shaft configured to hold the magnetic flux suppressing member and configured to slide the magnetic flux suppressing member along a longitudinal direction of the heating member; and a controller configured to control a rotational movement operation of the screw shaft so that the magnetic flux suppressing member is moved to a position depending on a width of the sheet. The controller is, during non-image heating, capable of executing an operation in a mode in which the screw shaft is rotationally moved so that the magnetic flux suppressing member is reciprocated at least once in a predetermined range.
