ABSTRACT:
A copier employing liquid developer in which the lower portion of a deep well in the liquid carrier extends downwardly into the space between a pair of shock absorbing machine base plate mounts to receive the supply of liquid developer for the machine. A motor housing in the upper portion of the well extends downwardly to approximately the upper level of liquid in the lower portion of the well when it contains a full charge of liquid. Each of a cleaning fluid supply motor and a developer electrode supply motor in the housing has a shaft which extends downwardly to a respective pump disposed in the liquid supply to drive the pumps respectively to supply liquid to the cleaning station and to the developer station. A splash plate extending over the top of the well prevents the escape of liquid from the well even with the machine at an appreciable angle from the horizontal. Shields are provided at various locations on the machine to prevent the accidental escape of liquid. Baffles inhibit free movement of liquid in the tank. Filler material in a developer applicator gap extending in the direction of the drum axis controls the flow of developer in the gap to facilitate copying when the machine tilts around an axis perpendicular to the drum axis.
