Abstract
In a transfer unit or method for an electrophoretic printing or copying apparatus, a rotating transfer element is provided at a first electrical potential arranged adjacent to a charge image carrier and that accepts toner images from the charge image carrier and supplies the toner images to a transfer printing station. An application element is provided adjacent to the transfer element that applies a cleaning fluid onto the transfer element to wet residual toner remaining after the transfer printing. An electrical potential element that recharges the wetted residual toner is provided after the application element and adjacent to the transfer element. A cleaning element after the potential element and adjacent to the transfer element is provided which is at an electrical potential selected so that an electrical field generated between the cleaning element and the transfer element draws the wetted residual toner towards the cleaning element.
