    • A fixing device includes a temperature measuring unit, configured to measure the temperature in regions that extend partially along the outer surface of a heating rotating body, which includes a resistance heating layer, in the circumferential direction and are aligned in the direction of the axis of rotation of the heat rotating body, and a control unit configured to sample temperatures, measured by the temperature measuring unit in each of the regions, over the entire outer surface of the heating rotating body in the circumferential direction by causing the heating rotating body to rotate while supplying a predetermined amount of power to the resistance heating layer, and to determine whether an abnormality has occurred in the resistance heating layer based on the difference between the maximum temperature and the minimum temperature among the sampled temperatures in each region.
    • 定影装置包括温度测量单元,该温度测量单元被配置为测量在包括电阻加热层的加热旋转体的外表面部分沿着圆周方向延伸并且沿轴向方向 热旋转体的旋转以及控制单元,其被配置为通过使加热旋转体旋转而在周向上在加热旋转体的整个外表面上测量由各个区域中的温度测量单元测量的温度 同时向电阻加热层提供预定量的电力,并且基于每个区域中的采样温度之间的最大温度和最低温度之间的差异来确定电阻加热层中是否发生异常。
