Abstract: A method, apparatus and composition for developing an electric field image associated with the surface of an object by disposing said surface close to but out of contact with a surface of a liquid developer at a development zone. An electric field is in the configuration of an image. The magnitude of the electric field, and the distance between the surface of the object and the liquid surface at the development zone are such that at the development zone the electric field at or approaching the zone, with or without the assistance of an external electric field, segmentally raises closely spaced tiny amorphous (individually non-image-defining) pseudopods from the liquid developer surface toward the surface of the object. The pseudopods rise from the liquid surface under the influence of a segment of the electric field image and the tips of the pseudopods and/or droplets separated from these tips arrive at the surface of the object under the influence of the same field.

Abstract: A method for developing a latent electrostatic image by passing the image close to but out of contact with a surface of a liquid developer at a development zone. The values of the magnitude of the charge of the image, the distance between the image segment and the liquid surface at the development zone, and the physical characteristics of the liquid are such that at the development zone the electrostatic field created by the segment of the image at the zone, with or without the assistance of an external electrostatic field impressed upon the development zone, raises pseudopods from the liquid developer surface which extend toward the carrier on which the electrostatic image is present. The pseudopods and/or droplets separated from the tips of the pseudopods leave the liquid surface under the influence of the electrostatic field created by the image segment.
