Abstract
A process unit which can be removably mounted in a main assembly of an electrostatographic copying machine. The unit comprises a housing enclosing an imaging member and, optionally, other processing means such as a development device, a cleaner, and a charge corotron. The transfer corotron, for transferring a toner image from the photoreceptor to a copy sheet is incorporated in the cassette housing, thus avoiding the need to provide a separate movable cover to protect the imaging member from contamination, physical damage, and light exposure when the cassette is removed from the main assembly of the copier.
