ABSTRACT:
An apparatus and method for developing a selected image by the electrostatic attraction of development fluid is disclosed. The system utilizes an interposer, adapted to be movably superimposed over a photoreceptor which preferably comprises the outer surface of a rotatable drum. A source of electrostatic charge for applying a first charge of a selected polarity to an area of the photoreceptor, and optical system for subsequently applying a light and shadow representation of the selected image to the area of the photoreceptor are also provided. The system further includes a source of electrostatic charge for applying a second charge, opposite in polarity from the first charge, to a portion of the interposer superimposed over the area of the photoreceptor. The portion of the photoreceptor is adapted to receive a quantity of electrostatic fluid, corresponding to the light and shadow representation applied by the optical system, when moved out of superimposition with the photoreceptor. A transfer station for transferring development fluid from the interposer to a copy medium is also provided, whereby the selected image is reproduced on the copy medium.
