Abstract
A method and apparatus capable of forming an image in an electrostatic apparatus having a photoconductor with a latent electrostatic image thereon. An electrical potential having a polarity opposite to the photoconductor is applied to a push development electrode thereby coating the image areas, as well as the background areas, of the latent electrostatic image. The background areas are cleaned by applying a potential having the same polarity as the photoconductor to a second pull development electrode.
