摘要： An image forming apparatus has an image forming station and a fixing unit. The fixing unit includes a coil for generating a magnetic field for induction heating the heating member. A first core made of a magnetic material is arranged fixedly around the coil. A second core made of a magnetic material is between the first core and the heating member in a generation direction of the magnetic field to form a magnetic path in cooperation with the first core and capable of changing a posture thereof. A shield made of a nonmagnetic metal is arranged along the outer surface of the second core to shield magnetism in the magnetic field and a magnetic shielding portion for changing the posture of the second core between a first posture where the shield shields the magnetism and a second posture where the shield does not shield the magnetism.

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。

Each of the cells includes a CPU, a memory, and range registers used for resource routing. At least one cell is used as a spare cell, and the remainder(s) of the cells is activated to provide an online system. The first module is programmed to provide a memory region of the online system with initial values to be set into the range registers of the spare cell in response to booting the online system. The service processor provides a copy of the initial values onto the memory of the spare cell in response to a request for activating the spare cell. The second module is programmed to put the initial values obtained from the copy into the range registers of the chipset on the spare cell.
