Title: Electrographic imaging apparatus and method

Abstract: Apparatus and method for imagewise controlling the flow of ions from a source toward an electrostatic image-bearing member utilize a predeterminedly electrically-biased slit means located between the ion source and the member. A portion of the slit means is maintained at a potential intermediate the image and background portions of the electrostatic image and so that ion flow toward the member is controlled in accordance with the image thereon. A substantially neutrally-charged mist is introduced between the slit means and the image-bearing member and charged and attracted to the member in accordance with the image.
