ABSTRACT:
A method is provided for developing a latent electrostatic image with marking particles through the process steps of: moving the surface of an image receiving member at a predetermined process speed; storing a supply of developer material comprising toner and carrier beads in a reservoirs said toner comprising electrically conductive core particles with an electrically insulating coating thereover; transporting marking particles onto an outer surface of a donor member to be delivered to a development zone adjacent the image receiving member; and inductive charging electrically conductive core particles of said toner onto said outer surface of said donor member prior to the development zone to a predefined charge level. Other features of the present invention will become apparent as the following description proceeds and upon reference to the drawings.
