摘要： The image forming apparatus includes a fixing portion, a temperature detection element, and a power control portion. The power control portion is capable of setting a first power supply control mode for supplying power according to the detected temperature for each one control cycle, a second power supply control mode for supplying power according to the detected temperature for each one control cycle and a third power supply control mode for supplying predetermined power, and switches, immediately before a leading edge of the recording material enters the fixing portion, a state of supplying the power in the first power supply control mode to a state of supplying the power in the second power supply control mode, and then switches the state of supplying the power in the second power supply control mode to a state of supplying the power in the third power supply control mode.

摘要： The image forming apparatus, in the case where image forming is performed on a recording medium whose size covers a position of a second temperature detection element perpendicularly disposed to the recording medium conveyance direction, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a first power supply control is switched to a second power supply control. In the case where image forming is performed on a recording medium whose size does not cover a position of the second temperature detection element, when the detected temperature rises to a predetermined temperature during execution of the first power supply control, a conveyance control portion executes a control for extending the conveyance interval of the recording medium. Thus, an unduly large temperature rise in the non-sheet passing portion is prevented, and a good quality image can be provided without glossy unevenness in one sheet.
摘要翻译：在检测到的温度在执行期间检测到的温度上升到预定温度的情况下，在其尺寸覆盖垂直于记录介质输送方向的第二温度检测元件的位置的记录介质上进行图像形成的情况下，第一电源控制，第一电源控制切换到第二电源控制。在尺寸不覆盖第二温度检测元件的位置的记录介质上进行图像形成的情况下，当在第一电源控制执行期间检测到的温度上升到预定温度时，输送控制部分执行用于延长记录介质的输送间隔的控制。因此，防止非片材通过部分的过大的温度上升，并且可以在一张片材中没有光泽不均匀的情况下提供高质量的图像。
