Abstract

Apparatus for developing an electrostatic image including a train of rotatable transport rollers adjacent the development zone, each roller having fixed magnets located therein to attract magnetic developer material to the periphery of the roller, which transports the developer from a developer sump to an elevated position and releases the material so that it cascades across the electrostatic image.
