ABSTRACT:
An apparatus for developing a latent image recorded on an imaging surface, including a housing defining a reservoir storing a supply of developer material including toner. A mag roll loads a toner layer onto a region of said outer surface of said donor member. A donor member, spaced from the imaging surface, moves toner on an outer surface of said donor member to a development zone opposed from the imaging surface. A shield, adjacent to said donor member and said development zone, said shield being electrical biased to generate a toner cloud between said shield and said donor member which said toner cloud releases to the development zone to develop the latent image, in response to the movement of toner on the outer surface of said donor member.
