Abstract
An apparatus which develops a latent image recorded on an image receiving member with developer material. A donor roll is positioned in a chamber of a housing having a supply of developer material. The donor roll transports a metered layer of developer material into contact with the latent image to develop the latent image. A conductive brush includes bristles having a diameter from about 6 to about 20 microns and contacts the metered layer of developer material on the developer roll. This substantially prevents the variation of triboelectric charge on the developer material on the donor roll so as to create a uniform charge level on the development material layer for development of the latent image.
