DEVICE AND METHOD FOR DEVELOPING LATENT ELECTROSTATIC IMAGES ABSTRACT OF THE DISCLOSURE A device for use in developing a latent electrostatic image formed on the image bearing surface of an electro- photographic belt as the belt is moving through an arcuate path includes a container having a quantity of liquid toner, The container includes a top wall that has a centrally located longitudinal slot and is shaped to conform to the path of the belt. A development electrode is located on the top surface of the top wall, A feed roller is rotatably mounted in the container and positioned so as to project out slightly from the slot in the top wall. In use, the container is positioned with the top wall close to and parallel to the arcuate path of travel of the belt and the feed roller close to hut not touching the belt. As the feed roller rotates, liquid toner is brought up close to the belt at which location the toner particles dispersed in the liquid toner are electrically attracted to and deposit on the charged portions of the belt.
