Apparatus and methods for image forming by liquid development under toner density control

摘要

To suppress a change in toner density in a liquid developer when forming an image, the available amount of toner is controlled be it on a developer roller (31) or an image carrier in accordance with a control signal received from a CPU. Any one of squeegee rollers (51,52,53) or the developer roller (31) selectively moves into and out of contact with a developer carrying surface, or is independently switched to various power sources via bias generators (119) to adjust toner and/or carrier consumption.
