Abstract: A fixing device of the present invention is equipped with a heated body whose fixing temperature applied to toner is changed and which is heated in accordance with a type of toner that has been discriminated by a toner type discriminating unit that discriminates types of toner classified at least as a result of their melting points differing. When toner with a relatively high melting point has been used, the fixing device is rotated on the basis of a limiting control unit that limits a number of sheets of recording paper that can be continuously fixed.
