Image forming apparatus with first and second power supply
First Claim
1. An image forming apparatus comprising:
- a first power supply unit configured to supply first output power;
a second power supply unit configured to supply second output power;
a switching unit disposed on an input side of the second power supply unit;
a monitoring unit configured to monitor the second output power supplied by the second power supply unit;
a power source control unit configured to turn the switching unit ON or OFF; and
a control unit supplied with the first output power, and configured to control the image forming apparatus,wherein, based on the second output power monitored by the monitoring unit having been lower than a threshold value since the switching unit is turned ON, the power source control unit turns the switching unit OFF and then turns back to ON in a state where the first output power is supplied to the control unit.

Abstract
An image forming apparatus includes a first power supply unit configured to generate first output power, a second power supply unit configured to generate second output power, a switching unit disposed on the primary side of the second power supply unit, a monitoring unit configured to monitor the second output power generated by the second power supply unit, a power source control unit supplied with the first output power, and configured to turn the switching unit ON or OFF, and a control unit supplied with the first output power, and configured to control operations of the power source control unit. When the second output power is lower than a threshold value, the power source control unit turns the switching unit OFF and then back to ON in a state where the first output power generated by the first power supply unit is supplied to the control unit.
