摘要： A total-current control unit is configured to add a fuser current of a fuser unit to a load current of the load to thereby obtain a total current to be supplied from a commercial power supply to the image forming apparatus, the total-current control unit being configured to control the total current to be at a predetermined limit value or less. An auxiliary power supply is configured to supply an auxiliary current to the load. The total-current control unit is further configured to provide first control to control the total current to be at the limit value or less and allow the auxiliary power supply to supply the auxiliary current to the load, thereby supplying, to the load, a current obtained by adding the auxiliary current to the load current, if an increase in the load current causes the total current to exceed the limit value.

摘要： A power supply unit selects one of drive power provided from an AC/DC conversion unit and that provided from a separation unit and outputs the selected drive power to a control unit and a transmission and reception unit continuously. If the AC/DC conversion unit and the separation unit both supply their respective drive powers, the drive power that has a higher voltage value, i.e., the first drive power, is selectively output. When the first drive power supplied is stopped, a diode transitions from the on state to the off state and a diode transitions from the off state to the on state. As a result the second drive power is selectively output.
