METALLIC DRUM USED FOR IMAGE BEARING MEMBER

摘要

PURPOSE:To facilitate manufacture and to reduce cost by rounding the bottom, i.e. the end side of a metallic drum and forming the end side and the circumference of the drum into one united body. CONSTITUTION:A typical example of an image bearing member is illustrated here. One end side 11 of a metallic drum 7 formed by the cold impact extrusion method is worked so as to form the driving member of an image bearing member, and the other end side is provided with a flange 13. The side end 11 is engaged with the hook 9 of a connecting gear 8 fixed to a main body 10 to transmit the torque of the gear 8 to the drum 7.
