Abstract: An apparatus for removing back-plated developer from a development device includes a shaft, cleaning media mounted about the outer surface of the shaft, means for loading the cleaning media against the development device, and means for rotating the shaft and the cleaning media, wherein the cleaning media removes back-plated developer from the development device. The cleaning media may include a fiber material having a plurality of flow paths. A fluid flow means can be provided to deliver a cleaning liquid to the cleaning media to flush at least a portion of the removed back-plated developer from the cleaning media.

Abstract: A development apparatus for developing a latent electrostatic image on an imaging substrate in a liquid electrographic imaging system includes a cleaning roller for removing back-plated developer from a development device such as a development roller, and a squeegee apparatus for.sub.-- removing both "drip-line" developer liquid and "wrap-around" developer liquid from the imaging substrate. The squeegee apparatus may include a squeegee roller having a crowned profile and a loading mechanism configured to achieve a uniform loading force across a pressure nip formed between the squeegee roller and the imaging substrate. The cleaning roller may include a fiber cleaning media and fluid delivery means for flushing back-plated developer from the cleaning media. The development apparatus also may include means for spacing the development apparatus relative to the imaging substrate without contacting the imaging substrate, thereby avoiding disruption of the motion quality of the imaging substrate.
