Battery Connection Detecting Device and Image Forming Apparatus Including the Same

An image forming apparatus comprising:

• a battery;
• a battery connection detecting device, which detects a connection state of the battery, and which comprises:
• a connecting unit, to which a battery is connected;
• a voltage detecting unit that detects a voltage value of the connecting unit, the voltage value detected by the voltage detecting unit being a detection voltage value;
• a switching unit that switches supply of charging power to the battery connected to the connecting unit based on the detection voltage value;
• and
• a connection detecting unit that compares at least one predetermined voltage value with at least one of the detection voltage value before the switching unit switches the supply of the charging power and the detection voltage value after the switching unit switches the supply of the charging power in order to detect whether or not the battery is connected to the connecting unit;
• a storage unit, which is connected to the battery, and which stores data related to image formation by electric power supplied from the battery;
• an image forming unit that forms an image on a recording medium using at least a part of the data;
• and
• a setting unit that sets a mode of executing detection processing by the battery connection detecting device.
