    • An image forming apparatus having (1) a main power supply unit (PSU), which converts an AC power source into an AC power and a first DC power, provides the AC power to a fusing unit, and provides the first DC power to a plurality of DC-powered units in the image forming apparatus, (2) a supplemental power supply unit, which accumulates the AC power source and provides a second DC power to the plurality of DC-powered units for a predetermined period, and (3) a controller, which increases or decreases the AC power to be provided to the fusing unit and selects the DC power source from the main PSU and the supplemental PSU by detecting that the supplemental PSU can provide the DC power to the plurality of DC-powered units or not. When the supplemental power supply unit can provide DC power to the Plurality of DC-powered units, the controller increases the AC power from the main power supply unit to the fusing unit and shortens the recovery time.
    • 一种图像形成装置,其具有:(1)将交流电源转换为交流电力和第一直流电力的主电源单元(PSU),将交流电力提供给定影单元,并将第一直流电力提供给 在图像形成装置中的多个直流动力单元,(2)补充电源单元,其累积交流电源并在多个直流供电单元中提供第二直流电力达预定时间段,以及(3) 控制器,其增加或减少要提供给定影单元的AC电力,并且通过检测补充PSU可以向多个DC供电单元提供DC电力,从主PSU和补充PSU选择DC电源 或不。 当补充电源单元可以向多个直流供电单元提供直流电源时,控制器将主电源单元的交流电力提高到定影单元,缩短恢复时间。
