摘要： In a widthwise direction of a heating roller perpendicular to a sheet conveyance direction, an amount of magnetic flux acting on the heating roller in the neighborhood of an end portion of the heating roller is larger than that at a center portion of the eating roller, so that it is possible to prevent a lowering in temperature at the heating roller end portion. Further, in a temperature range in which a temperature of the heating roller is higher than a fixation temperature and is lower than a heat-resistant temperature of a heating apparatus, the heating roller has a temperature area in which a resistance thereof is lowered, so that it is possible to reduce temperature rise in a differential area between a large-sized sheet passing area and a small-sized sheet passing area when a sheet having a size smaller than a maximum size (non-sheet passing portion temperature rise).
摘要翻译：在垂直于片材输送方向的加热辊的宽度方向上，加热辊的端部附近作用在加热辊上的磁通量大于进食辊的中心部位，可以防止加热辊端部的温度降低。此外，在加热辊的温度高于定影温度且低于加热装置的耐热温度的温度范围内，加热辊具有其电阻降低的温度区域，因此当尺寸小于最大尺寸（非片材通过部分温度升高）的片材时，可以减小大尺寸片材通过面积和小尺寸片材通过面积之间的差异区域中的温度升高。
