  • Patent number: 3955533
    Abstract: A squeegee roller system for removing excess developer liquid from the developed-image-bearing photoconductive surface of a drum or the like in which a freely rotatable squeegee roller having a covering of predetermined hardness is biased against the drum to cause excess developer to flow into a receptacle having a weir over which the liquid flows back to the supply tank and in which a fur or pile-covered cleaning roller contacting the squeegee roller is driven in the opposite direction from and at a speed slightly greater than that at which the drum drives the squeegee roller with lower portions of both rollers passing through developer liquid retained by the weir and in which a cleaning blade is biased into engagement with the cleaning roller.
