    摘要： In an image forming system, an image-bearing member having a photoconductor layer comprising an Si-based non-single crystal material is charged at a relatively low potential of 250 to 600 volts by a contact charging member in the presence of electroconductive fine powder. An electrostatic latent image formed on the image-bearing member is developed with a magnetic toner which includes magnetic toner particles comprising at least a binder resin and a magnetic iron oxide, and inorganic fine powder and electroconductive fine powder present at the surface of the magnetic toner particles. The magnetic toner has a weight-average particle size of 3-10 nullm and an average circularity of 0.950 to 0.995, and contains 0.05 to 3.00 % of isolated iron-containing particles.

    摘要： Deposition of background toner particles during tri-level image transfer from an imaging member to a final substrate is minimized. A front erase step is used prior to pretransfer corona treatment in order to reduce the background voltage level to substantially the residual voltage level of the photoreceptor imaging member used in the imaging process. When the image is subjected to pretransfer corona positively charged black and color background toner particles become negative and wrong sign black toner becomes more negative. Using negative transfer corona effects transfer of toner forming the black and color images and inhibits transfer of background toner.
