Abstract
A single image development and conditioning apparatus is disclosed for removing excess liquid carrier from a developed image developed in a liquid immersion development machine using liquid developer material having a first toner concentration. The single image development and conditioning apparatus includes a first zone located downstream of a coating device relative to a direction of movement of a surface bearing the developed image, a second zone located downstream of the first zone, and a third zone located downstream of the second zone. The first zone includes a first biased electrode for partially removing charged solid toner particles from background areas of the developed image. The second zone includes a second biased electrode for completing removal of charged solid toner particles from the background areas, and the third zone includes a third biased electrode. The first, second and third zones are arranged and biased so as to enable (i) removal, from the background areas, of liquid developer material consisting of liquid carrier and charged solid toner particles, and (ii) removal, from the image areas only, of excess carrier liquid, thereby creating a resulting toner image having a toner concentration significantly higher than the first toner concentration of the liquid developer material.
