摘要： A drum unit (20) for forming a toner image includes a cylindrical-shaped metal tubular member (31), a flange member (40) attached to one end of the metal tubular member (31) and a ground plate (50) attached to the flange member (40) and having an outer peripheral edge formed with a connection claw (52) that is so bent by the inner peripheral surface of the metal tubular member (31) as to bite into the inner peripheral surface for establishment of electrical conduction between the metal tubular member (31) and the ground plate (50). The flange member (40) has an edge, and the bending of the connection claw is carried out about a support point (412) defined by the edge. A calculational bending angle (θ) at which the connection claw (52) is bent about the support point (412) is set in the range of 10 to 45 degrees.
