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 conductive toner; a donor member for transporting toner on an outer surface of the donor member to a region in synchronous contact with the imaging surface; a toner layer is loaded onto a region of the outer surface of the donor member; induction charging the toner loaded on the donor member; then the toner layer is conditioned; next the donor member is moved into synchronous contact with imaging member to detach toner from the region of the donor member for developing the latent image; and residual toner discharged and removed from the donor member and returning the toner to the reservoir.
