Patent ID: 8712272

Claim:
An image heating apparatus comprising: a coil for generating magnetic flux; a rotatable heat generating member, which generates heat by the magnetic flux generated from said coil, for heating an image on a recording material; a plurality of magnetic cores provided outside said heat generating member and arranged in a rotational axis direction of said heat generating member; first moving means for moving at least a part of said plurality of magnetic cores from a first position to a second position spaced from said coil; magnetic flux adjusting means, movable between said magnetic cores and said heat generating member, for reducing the magnetic flux directed from said magnetic cores toward said heat generating member; and second moving means for moving, when a first magnetic core in a non-sheet-passing area of the recording material is moved to the second position by said first moving means and a second magnetic core adjacent to the first magnetic core in the non-sheet-passing area is disposed at the first position to heat the image, said magnetic flux adjusting means to a position corresponding to the second magnetic core.
