Kontrolle von Verunreinigungen für berührungslose Entwicklung in einem xerographischen Gerät

摘要

In a development system (38) for conveying toner to a latent image on a surface (10) in an electrophotographic printing apparatus, including a donor structure (40) spaced from the charge retentive surface (10) for conveying toner to a development zone adjacent the surface and an electrode structure (42) disposed between the donor structure (40) and the surface (10); contaminants are removed from the development zone by a flow of air away from the development zone.
