画像形成装置
Document Type and Number:
Japanese Patent JP4553914
Kind Code:
B2
Abstract:
An apparatus for image formation comprises a fixing unit, first to fourth switching units, a DC power supply unit, an accumulating unit, a charging unit, and a switching control unit. The first switching unit switches the state of connection between the fixing unit and a commercial power source. The DC power supply unit supplies another electric load of the apparatus than the fixing unit with DC power. The second switching unit switches the state of connection between the DC power supply unit and the commercial power source. The third switching unit switches the state of connection between the charging unit and the commercial power source. The fourth switching unit switches the state of connection between the accumulating unit and the electric load. Based on the state of conduction of the first switching unit, the switching control unit switches the states of conduction of the other three switching units.
