Abstract: Means for developing Xerographic images in which a developer applicator (21) is arranged to progressively apply a liquid developer to a latent electrostatic image on an image-bearing surface on a support member (3) and the surface is progressively pressed to a smooth conductive surface (19) to express excess developer liquid from the image-bearing surface to provide a relatively dry member containing the relatively dry developed image, a corona charging system (7) is included and also means (40-41-42) for multistage developement of color images.
