Abstract
A flexible latent image-bearing photoconductive element is driven through a U-shaped path to form a self-contained electrographic developer reservoir to which electrically conductive toner particles are supplied. A grounded, electrically conductive, apertured member positioned in the toner reservoir in close proximity to the image-bearing surface of the photoconductor imparts continuous motion to the toner particles as the image-bearing element moves therepast. The motion creates a sweeping action which reduces the amount of toner background present in a finished print.
