Abstract
An image forming apparatus includes a main housing, a process unit, and a fixing device including a lever. The main housing comprises an interlock switch that allows power to be supplied to a heater of the fixing device in an on-state and shuts off power to the heater in an off-state. The lever includes a holding portion and a switch contacting portion contactable with the interlock switch. In a case where the fixing device is installed in the main housing and the lever is located at a first position, the switch contacting portion is in contact with the interlock switch to set the interlock switch to the on-state. In a case where the fixing device is installed in the main housing and the lever is located at a second position, the switch contacting portion is separated from the interlock switch to set the interlock switch to the off-state.
