摘要: An apparatus for developing a latent image that contains a housing with a supply of a developer of carrier and toner and a coated toner donor member, which member is spaced from the surface on which a latent image Is being recorded. The apparatus also includes a means for advancing the developer material in the chamber of the housing and this means cooperates with the donor means and both means define a region wherein a substantially constant quantity of toner is deposited on the donor member. The apparatus further includes an electrode means positioned near the surface of a dielectric core roll and these electrodes are biased to detach toner from the donor member and to form a donor cloud for developing the latent image. The coated toner transport means can be comprised of a core with a coating of an oxidized polyether carbonate.
