Abstract
A liquid developing apparatus is provided for developing, with a liquid developer or toner, an electrographic latent image formed on an image bearing, charge retaining surface of a moving recording medium and thereafter wiping excess developer from the medium surface. The apparatus is designed to require only a single developer/wipe roll to perform the dual function of image development surface wiping. The single developer/wipe roll is supported for rotational movement in a direction opposite to the direction of movement of the recording medium and is in forward and leeward tangential engagement with a portion of the moving medium surface, respectively, to form a development apex and fluid seal between it and the recording medium surface and to wipe the recording medium surface to promote surface drying.
