1. Apparatus for enhancing liquid toner image transfer comprising:

  • an image bearing surface movable in a first direction;

    means for forming a liquid toner image on said image bearing surface;

    a second surface arranged for movement relative to said image bearing surface whereby portions of the image bearing surface and the second surface sequentially come into propinquity and subsequently move out of propinquity;

    potential impression means associated with at least one portion of at least one of the image bearing surface and the second surface for impressing a potential on said at least one portion; and

    means for energizing said potential impression means only when such portions are located at predetermined locations along the pathway, thereby to provide image rigidization,wherein said second surface is the surface of a roller and moves opposite to the movement of said image bearing surface thereby providing metering of excess liquid on said image bearing surface.
