Abstract:
1. An image heating apparatus, comprising: a coil; an image heating member which generates heat by magnetic flux generated by said coil to heat an image on a recording material; magnetic flux adjusting means for adjusting the magnetic flux so that an amount of magnetic flux from said coil toward an end portion of said image heating member is smaller than an amount of magnetic flux from said coil toward a central portion of said image heating member in a direction perpendicular to a conveyance direction of the recording material; energization control means for controlling energization to said coil so that a temperature of said image heating member is an image heating temperature which has been set preliminarily; and moving means for moving said magnetic flux adjusting means to a position, where the amount of magnetic flux from said coil toward the end portion of said image heating member is smaller than the amount of magnetic flux from said coil toward the central portion of said image heating member, at a temperature higher than the image heating temperature and lower than a Curie temperature of said image heating member which is higher than the image heating temperature and lower than a heat-resistant temperature of said image heating apparatus.
