PURPOSE:To provide a photoreceptor drum supporting device capable of simplifying the grounding structure of a photoreceptor drum and facilitating the attaching/detaching operation of the photoreceptor drum to/from the main body of an image forming device. CONSTITUTION:Bearings 46 and 47, at least either of which is formed of a conductive material, are fitted out both ends of the photoreceptor drum 31. A metallic supporting shaft 49 inserted through the center of the bearings 46 and 47 and brought into contact with the conductive grounding member 53 provided on the main body side of the image forming device is provided. Then, an engaging part 51 engaging with the supporting shaft 49 and preventing the movement of the supporting shaft 419 in the thrust direction with respect to the bearing 47 is provided, and the drum 31 is grounded by small number of parts, that is, only the bearings 46 and 47 and the supporting shaft 49. |
