Abstract:
1. An image forming apparatus comprising: an image forming section configured to form a toner image on recording material; and a power supply section including a voltage detection circuit configured to detect a voltage of a commercial alternating-current power supply, a first power supply configured to convert the voltage of the commercial alternating-current power supply into a direct-current voltage and to output a first voltage, and a second power supply having a rectifier circuit configured to be switched between a full-wave rectification state and a voltage-doubler rectification state in accordance with an output of the voltage detection circuit, the second power supply being configured to convert the voltage of the commercial alternating-current power supply into a direct-current voltage and to output a second voltage, wherein the image forming apparatus further includes a first switch section that is capable of disconnecting the second power supply from the commercial alternating-current power supply and that operates with the first voltage, and a second switch section that is capable of disconnecting the voltage detection circuit from the commercial alternating-current power supply and that operates with the first voltage, and wherein when the image forming apparatus is to be in a power saving mode, the second power supply is disconnected from the commercial alternating-current power supply by using the first switch section, and the voltage detection circuit is disconnected from the commercial alternating-current power supply by using the second switch section.
