ABSTRACT:
An embodiment includes developing unit having a first developer roller and a second developer roller in contact with the first developer roller. The first developer roller is adapted to transfer developed liquid developer to the second developer roller, and the second developer roller is adapted to transfer the developed liquid developer to a photoconductor. An electrode is separated from the first developer roller by a gap. The gap is configured to receive undeveloped liquid developer from a reservoir remote from the developing unit so that the first developer roller does not pass through undeveloped liquid developer contained in a reservoir within the developing unit.
