Board recording apparatus with reduced smudge

A board recording apparatus comprising a recording medium having a dielectric layer and an electrically conductive layer on one side of the dielectric layer, said recording medium being mounted for successive movement between an image formation station and a charge elimination station, said image formation station comprising recording electrodes arranged to apply voltages between said conductive layer and electrically conductive toner at selected regions on the other side of said dielectric layer to produce charges which cause said toner to adhere to the surface of said dielectric layer according to images to be recorded, said charge elimination station comprising a charge elimination electrode arranged to contact toner remaining on said recording medium and means for applying voltages to said charge elimination electrode of a polarity which may be opposite to that applied to said recording electrodes.
