摘要： In a fixing apparatus using an induction heating type of heating apparatus, there are provided an excitation apparatus that generates magnetic flux, an opposed core located opposite the excitation apparatus, a fixing belt that is induction-heated by the aforementioned magnetic flux, and magnetism masking elements that block magnetic paths corresponding to paper non-passage areas of fixing belt between the excitation apparatus and the opposed core. By blocking magnetic paths between the excitation apparatus and the opposed core by the magnetism masking elements, magnetic flux that induction-heats the fixing belt is effectively masked, and an excessive rise in temperature of paper non-passage areas of fixing belt is prevented.

摘要： A fixing apparatus can prevent an excessive rise in temperature of a paper non-passage area due to diverted flow of magnetic flux from a paper passage area of a heat-producing element to a paper non-passage area thereof has a small configuration. A center core is rotated by a rotation section, bringing cutaway parts to a magnetic path masking position, and the degree of magnetic coupling between the center core and a heat-producing roller is weakened, suppressing an excessive rise in temperature of paper non-passage areas of the heat-producing roller. With this fixing apparatus, switching of the intensity of magnetic coupling between the center core and heat-producing roller can be performed simply by rotating the center core. Also, with this fixing apparatus, it is not necessary for magnetism suppressing elements to be provided as separate members, enabling the configuration to be made simpler and less expensive.

摘要： A heating apparatus that enables an abnormally high temperature detection section that detects, when a heating element heated by means of electromagnetic induction reaches an abnormally high temperature, this abnormally high temperature, to operate speedily and reliably irrespective of the material and temperature characteristic of the heating element in a low-cost and compact configuration. In this apparatus, thermostat 301 is disposed on the same side as exciting coil 231 with respect to heat generating belt 210 and between winding bundles of a conductor wire of exciting coil 231. This allows coil guide 234 to hold both thermostat 301 and exciting coil 231 and allows these wires and terminals to be concentrated on one location, thus making it possible to reduce the number of parts and assembling man-hours and configure the body of the apparatus in a low-cost and compact configuration. Furthermore, thermostat 301 operates reliably when heat generating belt 210 reaches an abnormally high temperature irrespective of whether the material of heat generating belt 210 is a magnetic member or not and whether the temperature of heat generating belt 210 has exceeded a Curie temperature or not.

摘要： As a cooling mechanism that cools the entire paper passage area of a heat-producing belt, a rotational drive method of the heat-producing belt is employed and the heat-producing belt is cooled by rotational cooling by being made to idle when paper is not being passed through. An excitation apparatus and the above-described cooling mechanism are controlled so that recording paper is not passed through and the heat-producing belt is cooled while being heated over the heating width when the small-size recording paper is passed through until the temperature detected by a paper non-passage area temperature detecting sensor is at or below a predetermined fixing temperature. This fixing apparatus enables an excessive rise in temperature of a paper non-passage area of the heat-producing belt to be efficiently eliminated, and the temperature distribution of heat-producing belt to be made uniform in a short time.
