发明名称 IMAGE FORMING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide an image forming device capable of realizing simplification of a door open/close detecting device and cost reduction by reducing the number of detecting members. SOLUTION: In this image forming device provided with plural opening/ closing doors (upper door 20, lower door 21 and rear door 54), and equipping electrically insulating switches 41 and 55 for performing electrical insulation when the open/close door is respectively in a open state, and moreover equipping door sensors (detecting member) 36 and 47 for detecting the opening/closing state of the doors (upper door 20, lower door 21 and counter surface door 54), the number of the door sensors 36 and 47 (two) are made less than the number of the opening/closing doors (three), (upper door 20, lower door 21 and counter surface door 54).
