ABSTRACT:
A method and apparatus for delivering a uniform supply of toner to a development zone in an electrostatographic system is disclosed. Additional toner control in the form of magnets located near the donor member attract toner to the toner pick-up area and insure that a constant supply of toner reaches the development zone. The additional control of toner is especially useful when the supply of toner to the toner pick-up area is limited or the toner does not naturally flow to the toner pick-up area.. The toner supply is enhanced by a stationary magnet located adjacent the donor member and a magnet located on the charge metering blade. Both of the additional toner supply magnets form magnetic brushes of toner particles on the donor member surface, these magnetic brushes insuring a constant supply of toner to the development zone despite problematic development conditions.
