Abstract
A belt conditioner for non-impact electrographic printing apparatus using a flexible dielectric belt (including a conductive member forming a ground plane opposite the dielectric surface) has plural electrically conductive rollers engaging the dielectric charge receiving surface to effect controlled discharge of the surface to a uniform surface electrostatic voltage before direct charge deposition by a print head to form a latent electrostatic image. Corona discharge devices can also be utilized with the rollers to obtain the desired belt conditioning.
