Abstract
A xerographic system employing uncharged polarizable toner for developing the latent electrostatic images created on the system photoreceptor, with image exposure means having a laser, optical means for converting the laser beam into a sheet-like line of light for exposing the photoreceptor a line at a time, a total internal reflection type modulator means having an array of independently actuated electrodes in the path of the beam effectively to divide the beam into a line of image pixels in accordance with an image signal input; and for solid image areas, plural adjoining electrodes being actuated concurrently to provide simultaneously side by side beams which destructively interfere with one another and create nulls between adjoining pixels thereby enhancing development of solid image areas by said uncharged toner.
