Abstract:
A development system including a developer transport adapted for depositing developer material on an imaging surface having an electrostatic latent image thereon, comprising:a housing defining a chamber storing a supply of developer material comprising carrier and toner; a donor member, mounted partially in said chamber and spaced from the imaging surface, for transporting developer on an outer surface thereof to a region opposed from the imaging surface, said donor member having a magnetic assembly having a plurality of poles, a sleeve, enclosing said magnetic assembly, rotating about said magnetic assembly; a plurality of trim bars positioned about said donor member at predefined positions and spaced around said donor member, said plurality of trim bars progressively limits carrier bead chain growth thereby reducing developer bed height of said developer material on said donor member to a predefined developer bed height within a development nip.
