摘要： A development system including a developer transport adapted for depositing developer material on an imaging surface having an electrostatic latent image thereon, including a housing defining a chamber storing a supply of developer material including toner. A donor member is 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. The donor member has a magnetic assembly, which includes a plurality of poles, and a sleeve, enclosing said magnetic assembly and rotating about said magnetic assembly. A magnetic system generates a magnetic field to reduce developer bed height of said developer material on said donor member in a development zone.

The donor member has a magnetic assembly, which includes a plurality of poles, and a sleeve, enclosing said magnetic assembly and rotating about said magnetic assembly. A sensor measures a magnetic field of said donor roll at a predefined position on said donor roll. A magnetic system generates a magnetic field to reduce developer bed height of said developer material on said donor member in a development zone.
