Abstract
In an electromagnetic induction heating-type heating apparatus for moving a temperature decreasing member toward or apart from an effective position where a temperature in a predetermined area is decreased in order to take countermeasure against temperature rise at a non-sheet passing portion of a heating roller, a Curie temperature of the heating roller is not less than a predetermined image heating temperature and is less than a heat-resistant temperature of the heating apparatus.
