    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.

    摘要: A method for forming images including a) depositing an electrostatic latent image on a charge retentive surface of a photoreceptor member having a substrate; a charge transport layer with charge transport materials; and an overcoat layer positioned on the charge transport layer, wherein the overcoat layer includes a crosslinkable alcohol-soluble polyamide; and wherein the overcoat layer further includes additives having titanium dioxide, silica, a crosslinking agent, a deletion control agent, and a charge transport molecule; and b) applying a developer material via a development component to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface, wherein the developer material comprises emulsion aggregation toner, and further wherein at least one of the additives create a texturized surface on the charge retentive surface thereby reducing the contact area between the emulsion aggregation toners and the charge retentive surface enabling increased cleaning of toners.
