    • An excitation coil is arranged so as to be opposed to a rotatable heat generating roller of a conductive material, and on a rear side of the excitation coil, a core of a magnetic material is provided. The core is composed of a central core that is formed continuously in a rotation axis direction of the heat generating roller, and a plurality of U-shaped cores arranged at a distance from each other in that direction. A high-frequency current is applied to the excitation coil so that the heat generating roller 1 generates heat by electromagnetic induction. An additional coil is wound around the U-shaped core. Both ends of the additional coil are connected to a switching unit. When the switching unit is brought to a connected state, under an induction current generated in the additional coil, a magnetic flux in a direction in which a magnetic flux of the excitation coil is cancelled out is generated, so that heat generation of the heat generating roller can be suppressed. The switching unit is switched over according to a width of a paper sheet to be passed and a temperature distribution in the rotation axis direction. Thus, a uniform temperature distribution of the heat generating roller in the rotation axis direction can be maintained.
    • 激励线圈被布置成与导电材料的可旋转的发热辊相对,并且在励磁线圈的后侧设置有磁性材料的芯。 芯部由在发热辊的旋转轴线方向上连续形成的中心芯和沿该方向彼此间隔设置的多个U字形芯组成。 对励磁线圈施加高频电流,使得发热辊1通过电磁感应产生热量。 一个额外的线圈缠绕在U形芯上。 附加线圈的两端连接到开关单元。 当切换单元处于连接状态时,在附加线圈中产生的感应电流下,产生沿励磁线圈的磁通量抵消的方向的磁通量,从而产生发热量 辊可以抑制。 切换单元根据要通过的纸张的宽度和旋转轴方向上的温度分布而切换。 因此,可以保持发热辊在旋转轴线方向上均匀的温度分布。
