Abstract
An image heating apparatus includes a belt unit, a coil unit, a rotatable driving member, and positioning and urging mechanisms. The belt unit includes an endless belt to heat a toner image on a sheet at a nip portion. The coil unit opposes an outer surface of the belt and generates a magnetic flux for heating the belt. The driving member rotates the belt and forms the nip portion with the belt. The positioning mechanism positions the coil unit with respect to the belt unit and includes two positioning portions on each side of the coil unit with respect to a longitudinal direction thereof. The urging mechanism urges the coil unit toward the belt unit. The coil unit is supported by the belt unit at three of the four positioning portions.
