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 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.
