Abstract
A casing unitarily housing the photosensitive drum and developing device of a xerographic imaging system such that the thus composed imaging unit is retained in a predetermined operational position removably installed into a printing machine. The casing is configured such that when the imaging unit is removed from the printing machine, the imaging unit is retained in a posture equivalent to the predetermined operational orientation. Toner and developing agents are thus held in a steady state within the imaging unit, which particularly is an imaging unit in a lateral-transfer, vertical sheet-transport xerographic printing machine.
