    摘要： An apparatus for developing a latent image recorded on a surface, including a housing defining a chamber storing a supply of toner. A toner donor member is spaced from the image bearing surface and adapted to transport toner to a region opposed from the surface. A charging device is disposed in the chamber for ion charging the toner. An air injection system fluidizes the toner in the chamber. The injection system and a transport member cooperate with one another to define a region wherein a substantially constant quantity of toner having a substantially constant ion charge is deposited on the transport member. The toner is electrostatically transferred from the transport member to the donor member which contains interdigitated electrodes positioned near the surface of a dielectric core roll. An AC voltage is applied between the interdigitated electrodes to detach toner from the donor member so as to form a toner cloud for developing the latent image in an image on image process.

    摘要： Disclosed is an improved, simple, economical process for generating documents, such as personal checks, suitable for magnetic image character recognition, which process comprises generating such documents with conventional xerographic methods in a high speed electronic laser printing device, and wherein there is selected as the developer composition a magnetic toner containing from about 20 percent by weight to about 70 percent by weight of magnetite particles, and from about 30 percent by weight to about 80 percent by weight of toner resin particles of styrene copolymers, such as a styrene butadiene copolymer, a styrene n-butylmethacrylate copolymer, or polyesters, and wherein the carrier particles are comprised of ferrite cores, coated with various polymeric resinous compositions. There can also be included in the developer composition various additives such as collodial silica particles, and charge enhancing additives, and further conductive carbon black or insulating carbon black particles can be incorporated into the carrier polymeric resinous coating.
