Abstract
1,230,842. Conveyance of electrically charged sheets. CAPS RESEARCH Ltd. July 16, 1968, [April 25, 1967], No.33864/68. Heading G2H. Means for conveying charged sheets from liquid developer bath 5 having a spray device 19 to drying/ fixing means 9 comprises feed rollers 23, 25 which are covered with an insulative material, e.g. polyurethane, and engaged by conductive rollers 21, 27 respectively, held at a fixed potential, which may be earth potential, in which case charge collected by feed rollers 23, 25 is dissipated, or a potential of the same polarity as the toner particles, in which case toner particles are not picked up by the rollers from the sheet. (For Figure see next page)
