Abstract:
1. A developer system for an electrographic printer having a photoconductor element, comprising: a magnetic brush having a magnetic core surrounded by a toning shell that rotatably conveys a layer of developer to said photoconductor element; a sump containing a reservoir of developer; a self-metering conveyor roller for conveying developer from the reservoir to said toning shell of said magnetic brush having at least two magnetic poles of opposite polarity, an engageable metering skive in a developer flow path around said toning shell between said conveyor roller and said photoconductor element capable of engagement; and a driving assembly that rotates the conveyor roller at a saturation speed that saturates the flow of developer on the toning shell so that it is essentially constant when the conveyor roller speed is increased beyond the saturation speed if the engageable metering skive is engaged or not engaged.
