ABSTRACT:
An apparatus in which an electrostatic latent image recorded on a photoconductive member is developed with toner. A donor roll, spaced from the photoconductive member, transports toner to a development zone adjacent the photoconductive member. An electrode member is positioned in the development zone between the photoconductive member and the donor roll. A magnetic roll transports carrier granules and toner particles to a loading zone adjacent the donor roll. In the loading zone, toner particles are attracted from the magnetic roll to the donor roll. A sealing member has a magnetic field induced therein by the magnet in the magnetic roll. The sealing member attracts carrier granules thereto preventing the carrier granules for being transported to the donor roll.
