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： An image forming machine equipped with a transfer belt unit includes a safety detecting means for detecting the completion of setting of an opening/closing member constituting the image forming machine, and a controlling means for controlling the operation of a driving means for a driving roller on the basis of a signal from the safety detecting means. When the safety detecting means signals the completion of the setting after signaling the incompletion of the setting, the controlling means controls the driving means so as to perform a reverse driving, thereby driving the driving roller reversely by a predetermined amount.

摘要： A fixing unit for fixing a toner image onto paper has a member to be heated and a pressurizing member configured to press against the member to be heated and fix the toner image to the paper. At least one coil surface is disposed along one surface of the member to be heated and includes a coil to generate a magnetic field for inductively heating the member. A magnetism shielding member is disposed near the coil surface. A switch includes a first member to allow passage of the magnetic field and a second member to prevent passage of the magnetic field. The amount of heat for the member when the switch is in a first position where the second member is close to the magnetism shielding member is smaller than when the switch is in a second position where the second member is distanced from the magnetism shielding member.

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。
