    摘要： 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.

    摘要： In a scavengeless development apparatus, an electrode wire is disposed between a donor roll and a latent image to form a powder cloud of toner to develop the latent image. The donor roll includes a section of increased diameter spaced away from the latent image, and the electrode wire is disposed in sliding contact with the section of increased diameter to obtain a consistent spacing from the main length of the donor roll.

    摘要： A developer unit adapted to develop a latent image with toner particles. The unit includes a housing defining a chamber for storing a supply of toner particles in the chamber. The unit also includes a donor roll including an electrically non-conductive circumferential surface having a conductivity less than 10.sup.-8 (ohm-cm).sup.-1 and having a central region and opposed marginal regions disposed on either side of the central region with the diameter of the central region being less than the diameter of the opposed marginal regions. The donor roll is spaced from the latent image to form a development zone. The unit further includes an electrode member which is positioned in the development zone adjacent opposed marginal regions and spaced from the central regions of the donor roll. The electrode member is electrically biased to detach toner particles from the donor roll to form a toner powder cloud in the development zone with toner particles from the toner cloud developing the latent image.
