Abstract (en)

[origin: WO2006090352A1] A binary image development printing system (100) using liquid toner, the system comprising: a) a developer member (104) configured so its surface moves in a first direction; b) at least one electrode (106, 108), separated from the developer surface by a gap (110) running part of the way around the developer surface; c) an inlet (111) for introducing the liquid toner into the gap (110); d) a voltage source (109) configured to apply a voltage difference between the electrode (106, 108) and the developer surface, sufficient to cause at least some toner particles in the liquid toner to be deposited in a toner layer (112) on the developer surface, when the liquid toner is introduced into the gap through the inlet (111); and e) a pump (138, 140) which causes a portion of the liquid toner introduced into the gap (110) through the inlet (111) to flow along the gap in a second direction opposite to the first direction, wherein the portion is more than 30% and/or wherein the portion is sufficiently great so that, when the voltage difference is applied, most of the toner particles deposited in the toner layer (112) come from said portion.
