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