Abstract
A photoconductive drum is rotatably mounted on a shaft and is axially movable for removal from the apparatus. One or more guide rollers are disposed below and adjacent to one end of the drum so that a small axial movement of the drum will move the drum into supporting engagement with the guide rollers. The drum rolls over the guide rollers for easy removal from the apparatus. The guide rollers may also be movable so that the drum is moved into supporting engagement with the guide rollers and the drum and guide rollers are then removed from the apparatus in a unitary manner.
