ABSTRACT An apparatus for the liquid processing or development of a latent image on an electrostatic or photographic material is disclosed wherein a single liquid, usually referred to as a monobath, can be used to develop the latent image on a photo- graphic material or a liquid developer which comprises a liquid carrier and toner particles can be used to develop a latent electrostatic image. The apparatus comprises a first member having an open- end chamber that is interconnected to a reservoir for at least one processing fluid and is provided with sealing means for retaining the processing liquid in proper relation to the image area being developed. The sealing means comprises at least one peripheral member that engages the latent image-bearing surface when the material is arranged in the processing apparatus. A second member having an open-end chamber and a transparent support which encloses the open end is movable relative to the first member for clamping the photosensitive material therebetween via the sealing means. Suitable means is interconnected to the second member for moving the batter into a material clamping position relative to the first member. After the processing liquid has been applied for developing the latent image. air under pressure can be directed into the chamber. The application of air under pressure removes any residual liquid that may have accumu- lated at the edge of the scaling member. The air also squeegies any remaining liquid off the surface of the material and carries it away in a mist or in a finely atomized condition. The apparatus is therefore intended primarily for n cycle of operation with respect to a strip or sheet of material having at least one latent image ?hereon and that can be moved intermittently rather than continuously relative to the apparatus. a
