Abstract
An apparatus for developing a latent electrostatic image on a charge retentive surface moving in a process direction with toner, the apparatus comprising: a supply of toner; a donor structure spaced from the charge retentive surface for conveying toner from the supply of toner to an area adjacent the charge retentive surface, a device for applying an alternating current directly to the donor structure to create an alternating electrostatic field between the donor structure and said charge retentive surface to produce a toner cloud adjacent the charge retentive surface for developing the latent electrostatic image thereon; and an edge enhancement device, adjacent to the donor structure, for redistributing toner on the developed latent electrostatic image.
