Abstract
A fixing apparatus and an image formation apparatus therewith are disclosed. According to the fixing apparatus, a heating range that is heated by electromagnetic induction caused by a current flowing through a coil unit is finely tunable by covering a part of a core unit with a shielding member. Further, the core unit has a projecting section at an end of the core unit, which projecting section projects toward the coil unit in comparison with the central part of the core unit.
