Abstract
An apparatus for developing a latent image recorded on an imaging surface with toner, including: a developer housing including a reservoir for storing a supply of toner; a donor member for transporting toner on an outer surface of the donor member to a development zone; a purging system, adjacent to the donor member, for removing toner the donor member and the reservoir.
