PURPOSE:To stabilize the slide contact of the substrates of both of a small diameter photosensitive drum and a small diameter developing roll with the fixed shafts being the centers of rotation of them. CONSTITUTION:In a conductive cylindrical body, the continuity of a spring member 6 and a fixed shaft 2 is taken through the slide plate 7 provided vertically with respect to the fixed shaft 2. Therefore, even when a small diameter cylinder 1 is used, the foot of the spring member 6 can be made long. Therefore, the contact with a slide surface is stabilized and the image flaw or unnecessary radiation noise caused by the instability of the contact resistance of a slide contact part can be prevented. |
