Document Type and Number:
Japanese Patent JP5790197
Kind Code:
B2
Abstract:
An image forming apparatus includes a main power supply; a power generation unit configured to generate electric power with natural energy; a secondary battery configured to serve as a power supply source while the electric power is not supplied from the main power supply, the secondary battery being charged with the electric power generated by the power generation unit; a voltage detector configured to detect an output voltage of the secondary battery; and a switching unit configured to switch the power supply source from the secondary battery to the main power supply when the output voltage becomes equal to or lower than a first threshold, and switch the power supply source from the main power supply to the secondary battery when the output voltage becomes equal to or higher than a second threshold that is higher than the first threshold.
