Abstract
A liquid electrophotographic developing apparatus including a developing unit and a plurality of air transport members. The developing unit has an elongated opening disposed adjacent to a moving image-bearing surface of a photoreceptor, and it is used for converting an electrostatic latent image into a toner image. Electrodes formed within the elongated opening provide an electric field to charge toner particles in a liquid developer. The air transport members are provided around the elongated opening of the developing unit, and airflow therein has a predetermined air pressure to transport unused developer away from the image-bearing surface while permitting toner particles in the liquid developer deposited on the image-bearing surface to be retained by the image-bearing surface.
