Abstract

PURPOSE:To facilitate mounting and dismounting operation of a drum and to reduce accumulated errors of fitting positions, by forming a pluralities of plates in one body with the drum cylinder in this inside and by fixing bearings on the ends of protrusions and on both ends in the drum shaft direction. CONSTITUTION:On the inside of cylinder 19, 4 protrusions 21 are provided in the direction of a drum shaft 20, and on the ends 21a and on both ends in the shaft direction bearings 22 are fixed. This simple structure can facilitate remarkably mounting and dismounting operation of the drum, and reduce accumulated errors of its fitting positions. Since ends 21a of protrusions 21 guide drum shaft 20, impairing or scratching of the circumferantial devices or the surface of drum 7 due to contact can be prevented. In addition, protrusion 21 can prevent cylinder 19 overheat due to corona discharge or the like as cooling fins.
