ABSTRACT:
A liquid development apparatus for developing electrostatic latent images borne on the surface of an image bearing medium. The apparatus comprises leading and trailing squeeze rollers in horizontally spaced relation, means disposed between the squeeze rollers and spaced apart from the surface a short distance for selectively and uniformly applying a plurality of liquid developers and a rinse liquid to the surface, and means disposed at the rear side of the trailing squeeze roller for neutralizing or dissipating the residual charge remaining on the surface after development. These components are all mounted to a carriage adapted for reciprocation relative to the surface so that the electrostatic latent image is successively subject to developing, squeezing, and charging in this order during the movement of the carriage in the forward direction, and it is subject to rinsing during the movement of the carriage in the rearward direction. Such movement is repeated desired times to make a multi-colored print.
