PURPOSE:To provide an electrophotographic image forming device having a heater for heating a photosensitive drum to a determined temperature in which the erroneous installation of a drum unit caused between products having different specification voltages is prevented. CONSTITUTION:In an electrophotographlc image forming device having a structure in which a photosensitive drum 22 is held at a determined temperature by a heater 23 built in the photosensitive drum 22 of a drum unit 20, and an electricity is feed to the heater 23 throughconnector 30 consisting of a socket 31 provided on a device body 10 side and a plug 32 provided on the drum unit 20 side, the socket 31 is arranged in a different position according to the specification voltage of the device body 10, and the plug 32 is also arranged in a different position, corresponding to the specification voltage of the heater 23. Otherwise, a terminal in the socket 31 is arranged in a different position corresponding to the specification voltage of the device body 10. |
