ABSTRACT:
An electrostatic copying machine wherein the copying drum and the cleaning unit for the photosensitive layer of the drum are mounted in the plastic casing of a module which can be inserted into the stationary main portion of the housing upon pivoting of a cover to open position. The main housing portion and the cover carry rollers which automatically center the copying drum of a properly inserted module when the cover is moved back to closed position. The casing of the module has a vessel for a supply of developing or fixing liquid and means for automatically feeding liquid to a tank in the main portion of the housing when the supply of liquid in the tank descends below a predetermined level. One of the rollers can be driven by the motor of the copying machine to rotate the drum when the latter is properly centered in the housing.
