ABSTRACT:
A cleaning system for a liquid developer electrophotographic copier includes a roller formed with a body of resilient material, such as a closed-cell elastomer, having externally exposed, internally isolated surface cells. The roller is mounted to extend across the imaging surface in contact therewith and is driven to move the roller surface relative to the wet imaging surface to scrub the imaging surface and concomitantly under the action of the roller surface open cells to draw from the imaging surface liquid carrying toner effectively to dry the imaging surface. A small-radius edge is disposed in trailing engagement with the roller surface to deform the roller material sufficiently from the surface cells to be carried away for reuse or disposal.
