    摘要： An image forming apparatus includes a main power unit that outputs a first DC power and an auxiliary power unit that outputs a second DC power to the components of the image forming apparatus. The auxiliary power unit includes a rechargeable capacitor. A measuring unit measures performance of the capacitor and a determining unit determines performance insufficiency of the capacitor based on the measured performance and the system configuration of the image forming apparatus. The performance is, for example, changes in a capacitance of the capacitor with time. When the determining unit determines performance insufficiency of the capacitor, a control unit adjusts, for example, a use range of the capacitor.

    摘要： A power supply device includes a first power-supply unit to input external power and to output first power supplying a predetermined constant voltage to a load, a second power-supply unit to accumulate charge and to output second power to the load in parallel with the first power being supplied from the first power-supply unit, and a controller to output a control signal to prevent the second power-supply unit from supplying power in case of a current increase due to a dynamic load change, and to cause the first power-supply unit to supply power for the dynamic current increase. The first power-supply unit supplies power having a current value smaller than a predetermined maximum current of the first power-supply unit. The second power-supply unit supplies power for a shortfall current exceeding the predetermined maximum current of the first power-supply unit.

    摘要： An image forming device includes a power supply part which supplies AC power and DC power to a load of the image forming device. A capacitor stores DC power therein and discharges the stored DC power to the load. A control unit is adapted to control the power supply part and the capacitor so that the DC power stored in the capacitor is supplied to the load during a predetermined period after power-up of the image forming device or return from a low-power mode occurs.

    摘要： Stored DC power is supplied to a load after a return to a normal-power mode or a power-up of an image forming device. An auxiliary power supply does not supply the stored DC power to the load, and a main power supply supplies AC and DC power to the load if it is determined that a predetermined processing is performed upon a starting of the image forming device. The auxiliary power supply supplies the stored DC power to the load, it is determined whether a predetermined time has elapsed, and the main power supply does not supply the AC and DC power to the load if it is determined that the predetermined processing is not performed upon the starting of the image forming device. A decision whether the predetermined processing is performed is based on at least one of a number of sheets, an elapsed time, and an environmental temperature.
