In this apparatus, the Currie temperature Tc of the magnetic adjuster material heated by electromagnetic induction is set to 220 degrees C. or below and the fixation setting temperature of a heating member corresponding to the portion where a recording material passes during continuous sheet feed is set lower than a value than the temperature at which the relative magnetic permeability of the magnetic adjuster material begins to decrease.

摘要： A heat generating roller, fixing equipment and an image forming apparatus in which warm-up time is shortened while preventing excessive temperature rise and good fixing performance is realized by preventing occurrence of offset. In the heat generating roller, fixing equipment and image forming apparatus, the heat generating roller is formed principally by laying a high permeability conductive layer and a nonmagnetic conductive layer in layer. When a voltage is applied from a power supply (not shown) to an exciting coil and an AC current flow through it, magnetic flux is generated around the exciting coil and a magnetic field is formed. Since the heat generating roller has the high permeability conductive layer and the nonmagnetic conductive layer laid in layer, magnetic coupling of a system consisting of the heat generating roller and the exciting coil is good at the time of low temperature and heat generation of the heat generating roller is accelerated. When the Curie point is exceeded, skin depth becomes deep and skin resistance decreases, which suppresses generation of Joule's heat and reduces heat generation of the heat generating roller.
