Abstract
An apparatus has a hollow drum detachably provided on the apparatus and a drive device fixedly provided on the apparatus for drivingly rotating the drum. The drive device includes a flywheel for giving an increased moment of inertia to the drum. The drum includes a flange having an open end. A part of the flywheel is inserted into the open end of the flange when the drum is attached to the apparatus. The drum is separated from the flywheel, so that the drum as removed is lightweight and easy to handle. The drum may include a photosensitive surface and constitute a part of a process unit.
