Abstract
A development system optimized for efficient development of an electrostatic latent image on an imaging surface. The development system includes a development material sump, a magnetic developer roll including a rotatable sleeve having located therein a rotatable magnetic core, and a developer material delivery system for providing a metered supply of developer material to the rotatable sleeve. One or more stationary magnetic shunts are located with respect to the magnetic core, sleeve, and/or developer material delivery system so as to block the magnetic field effective for attracting developer material to the sleeve, thus allowing disengagement of the developer material therefrom at a drop-off zone.
