    • An image heating apparatus of electromagnetic induction heating-type capable of providing a proper relative heat-generation distance with a magnetic flux generation member even when the magnetic flux generation member is bent by its own weight or thermally deformed includes at least an exciting coil, a holder for holding the exciting coil, and a rotatable fixation roller for generating heat by magnetic flux from the exciting coil to heat a material to be heated. The holder has an outer diameter φd1 at a central portion and an outer diameter φd2 at an end portion in a longitudinal direction of the holder perpendicular to a conveyance direction of the material to be heated. The outer diameters φd1 and φd2 satisfies: φd1
