Abstract
Liquid toner conditioning apparatus for use in an electrophotographic color printer and including a stabilizing roller positioned adjacent to the surface of a photoconductive drum and operative for transforming discrete color toner particles on the surface of the drum into a stabilized unitary polymeric film structure which may be directly transferred onto an adjacent print medium. Advantageously, the stabilizing roller will include an inner core member which may be heated as well as connected to a source of either AC bias or DC bias or both. This stabilizing and toner conditioning roller further includes a soft elastomeric roller cover positioned around the periphery of the inner core member and has a smooth outer surface which makes direct contact with the developed toner layers on the surface of the adjacent photoconductive drum.
