Abstract
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.
