Abstract
Provided is an image forming apparatus capable of detecting the ON/OFF state of each of two interlock switches connected in series to a power line, and detecting the opening/closure of each of two covers. The first and second interlock switches are set on/off according to the opening/closure of the first and second covers respectively. The first interlock switch is connected to a supply voltage when the first interlock switch is on, and is connected to a detection voltage being lower and on which the load does not operate when the first interlock switch is off. A control part detects the opening/closure of the first cover and the second cover based on a voltage on the power line between the first interlock switch and the second interlock switch and a voltage on the power line between the second interlock switch and the load.
