ABSTRACT:
Electrophotographic copying apparatus for use with a composition containing spacing particles to provide a gap between the developed image on the photoconductor and the carrier sheet to which the image is transferred, in which a reverse roller reduces the excess liquid on the developed image before transfer, which reverse roller is a metering device biased to a potential greater than the non-image areas of the developed image. The bias on the metering device impresses a potential of opposite polarity to the polarity of the toner particles to hold the toner particles forming the developed image on the photoconductor.
