Abstract:
1. An image heating apparatus, comprising: a coil for generating magnetic flux by energization; a rotatable belt member for generating heat by magnetic flux generated by said coil to heat an image on a recording material; operation means for operating said belt member so as to change a distribution of an amount of a gap between said coil and said belt member in a width direction of said belt member perpendicular to a conveyance direction of the recording material; and control means for controlling said operation means so that, when a recording material having a predetermined size in said width direction smaller than a conveyable maximum size in said width direction is conveyed, said operation means operates said belt member so that a gap between said belt member and said coil located opposite to the non-conveyance area of the recording material having the predetermined size is larger than a gap between said belt member and said coil located opposite the conveyance area of the recording material having the predetermined size.
