ABSTRACT:
A fixing apparatus and an image formation apparatus are disclosed. The fixing apparatus includes two or more heaters with temperature detecting function that generate heat with electric current and detect temperature; a heating unit that includes the heater with the temperature detecting function; a film, a surface of which slides on the heating unit; a thermal fixing unit that is heated by the heating unit through the film for fusing a toner image that is yet-to-be fixed on a recording paper at a predetermined fixing temperature; a pressurization roller for pressing the recording paper to the thermal fixing unit; and a temperature control unit for controlling the temperature of the heater to be a predetermined temperature based on the temperature of the heater detected by the heater with the temperature detecting function.
