摘要： A fixing apparatus of the present invention for an electronic induction heating system includes a heat roller and a magnetic excitation coil that generates Joule heat within the heat roller. The fixing apparatus includes a coil positioner that positions the magnetic excitation coil around a portion of a periphery of the heat roller, a fixing roller that fixes toner image on a recording medium, and a belt that contacts a portion of a periphery of the heat roller and the fixing roller to conduct the generated heat from the heat roller to the fixing roller. The coil positioner further has a surface of first curvature substantially identical to a curvature of a periphery of the heat roller at an opposition area, the opposition area being opposite to a contact area where the heat roller makes contact with the belt. The coil positioner is spaced from the belt by a predetermined distance. The coil positioner further has a first extension extending from a first end of the opposition area of the coil positioner and a second extension extending from a second end of the opposition area of the coil positioner. The first extension and the second extension are spaced from the belt distances larger than the predetermined distance.

摘要： A heating roller performs electromagnetic induction heating, and includes a first exciting coil that heats the heating roller, a first degaussing coil that decreases magnetic fields of the first exciting coil, and a first axial direction core that guides magnetic fluxes, to make up a magnetic circuit between the first axial direction core and the heating roller. The width of a heat zone is controlled in agreement with a sheet feeding area. Thus, the capability to control a temperature increase in a non-sheet-feeding area of the heating roller is enhanced. Power can be saved during continual feeding of small recording sheets.
