Abstract:
1. An image heating apparatus comprising: a rotatable heating member configured and positioned to heat a toner image on a sheet; an excitation coil provided outside of said rotatable heating member and configured and positioned to cause electromagnetic induction heat generation in said rotatable heating member; a magnetic core provided opposed to said rotatable heating member with said excitation coil between said magnetic core and said rotatable heating member and configured and positioned to direct a magnetic flux produced by said excitation coil to said rotatable heating member; a retracting mechanism configured to retract said magnetic core from said excitation coil; a coil holder configured and positioned to hold a side of said excitation coil adjacent to said rotatable heating member; and first and second pressing members configured and positioned to press said excitation coil against said coil holder in outside portions beyond said magnetic core in a longitudinal direction of said rotatable heating member, respectively.
