Patent ID: 7098430

Claim:
An image heating apparatus for heating an image on a recording material by using a heat generating member which generates heat by magnetic flux generated by magnetic flux generation means for generating magnetic flux by energizing a coil, said image heating apparatus comprising: a magnetic flux adjusting member for adjusting magnetic flux acting on the heat generating member by changing its position relative to the magnetic flux generation means; drive means for driving said magnetic flux adjusting member to be movable between a first magnetic flux adjusting position and a second magnetic flux adjusting position so as to adjust a distribution of magnetic flux acting on the heat generating member in a widthwise direction perpendicular to a magnetic material conveyance direction of the heat generating member; energization control means for controlling energization of the coil so that a temperature of the heat generating member reaches a target temperature; and change means for changing the target temperature; wherein when the temperature of the heat generating member in an end area in the widthwise direction perpendicular to the recording material conveyance direction of the heat generating member is increased during continuous heating of a recording material having a size smaller than an available maximum size of the recording material, the recording material is passed through said image heating apparatus by changing the target temperature to a lower temperature by said change means and in this state, said magnetic flux adjusting member is driven by said drive means when the temperature of the heat generating member in the end area is increased.
