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： An image heating apparatus is provided that enables the entire width of a heat-producing medium to be heated uniformly and an excessive rise in temperature to be prevented, without making the configuration complex. In a fixing unit 19 in which this apparatus is applied, a fixing belt 112 is an annular member that has an inner peripheral surface and an outer peripheral surface, and produces heat through the action of magnetic flux. An exciting coil 120 is located in proximity to the outer peripheral surface of fixing belt 112, and generates magnetic flux that acts upon fixing belt 112. A suppression member 650 is located in proximity to inner peripheral surface of fixing belt 112, and reduces, of the magnetic flux generated by exciting coil 120, magnetic flux that acts upon a paper non-passage area of fixing belt 112.

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： An electromagnetic induced heating roller (21) comprises a core member (24), an elastic layer (23), induction heating layer (22), and a mold release layer in this order from inside to outside. Further, a magnetic shield layer for preventing a magnetic flux from penetrating into the core member (24) is interposed between the induction heating layer (22) and the core member (24). Out of an alternating magnetic field from a magnetic field generating means, a leakage flux having penetrated through the induction heating layer (22) is trapped by the magnetic shield layer. As a result, most of the impressed alternating magnetic flux is consumed for heating the heating layer (22), resulting in an improvement in the heating efficiency. A trouble is prevented which is generated by heating the bearing of the core member (24).
