摘要： A fixing apparatus used in an image forming apparatus has a fixing member for fixing toner on paper and a pressure member making contact therewith to form in between a nip through which paper is passed. The fixing member has a support member formed of a ferromagnetic material and a heating layer formed adjacent thereto in the form of a thin layer of a non-magnetic, electrically conductive material. When a high-frequency electric current is passed through an exciting coil that is combined with the fixing member, the fixing member produces a high-frequency magnetic field, thereby produces induced eddy currents in the heating layer of the fixing member, thereby produces Joule's heat in the heating layer, and thereby heats the fixing member. A leaking magnetic flux is absorbed by the support member of the ferromagnetic member, and thus has reduced influence on metal parts located around the fixing apparatus.

摘要翻译：用于图像形成装置的定影装置具有用于将调色剂固定在纸上的固定构件和与其接触的压力构件，以形成在通过纸张的辊隙之间。固定构件具有由铁磁材料形成的支撑构件和与其相邻形成的非磁性导电材料薄层形式的加热层。当高频电流通过与固定构件组合的励磁线圈时，固定构件产生高频磁场，从而在固定构件的加热层中产生感应涡流，从而产生焦耳热在加热层中，从而加热固定构件。泄漏的磁通被铁磁构件的支撑构件吸收，因此对位于定影装置周围的金属部件的影响减小。

摘要： A fixing device for image forming apparatus includes: a first nip member in a shape of an endless belt and a second nip member that rotates while pressed against the first nip member. A heat source heats at least one of the nip members. A pressure receiver receives pressure applied to the first nip member from the second nip member. A sliding contact has a contact surface that makes sliding contact with an inner surface of an axial end of the first nip member. A supporting mechanism supports the sliding contact to displace the contact surface thereof away from the pressure receiver as the first nip member moves away from the sliding contact along the axial direction. The displacement increases frictional forces between the contact surface and the inner surface of the first nip member, thus suppressing axial displacement of the first nip member from the sliding contact.
