摘要：PURPOSE:To form a drum shaft with soft materials and make bearings of the drum shaft unnecessary by connecting the first hard leaf spring to the drum shaft through the second soft leaf spring. CONSTITUTION:Drum flanges 12 arranged in both end parts of a photosensitive drum 11 are pierced by a drum shaft 13 and are supported freely rotatably. A hard leaf spring 14 as the first conductive member is fixed to the inside face of each drum flange 12 by welding. Plural first claw parts 15 are formed on the outside peripheral part of the leaf spring 14 and are pressed to the inside face of the photosensitive drum 11. The second claw parts 16 are formed on the flat spring 14 also. A soft leaf spring 17 as the second conductive member is provided between each drum flange 12 and the leaf spring 14, and a tongue piece 18 is formed in the center part of the leaf spring 17. The tongue piece 18 is pushed by the claw part 16 of the leaf spring 14 and is brought into contact with the peripheral surface of the drum shaft 13. Since the soft leaf spring 17 is brought into contact with the drum shaft 13 in this manner, it is unnecessary to make the drum shaft hard.
