PURPOSE:To prevent a mis-operation from being performed, by providing a releasing means which releases a designated image forming mode in case of detecting the closure of a switch cover by a cover open/close detecting means while no image forming operation is executed. CONSTITUTION:The titled device is provided with the cover open/close detecting means 240 which detects the opening/closing state of the switch cover 211, and the releasing means which releases the designated image forming mode in case of detecting the closure of the switch cover 211 by the cover open/close detecting means 240. By closing the switch cover 211 while no image forming operation is executed, mode designation by a switch arranged in the switch cover 211 is released. In other words, it is possible to easily judge the execution of the mode designation by the switch from the opening/closing state of the switch cover 211. Thereby, it is possible to easily discriminate whether or not the switch in the switch cover 211 is inputted without opening the switch cover 211. |
