ABSTRACT:
Magnetic brush developer apparatus which alleviates any developer material starvation in the area of contact with a charge pattern-bearing member. Such apparatus develops an electrostatic charge pattern on a member by contacting the member with developer material, including magnetic particles, transported toward and away from the charge pattern-bearing member by an applicator member. The transported developer material is magnetically agitated in the area of contact with the charge pattern-bearing member in a direction which includes at least a component perpendicular to the transport direction, whereby intermixing of the developer material in such contact area is substantially improved to reduce any propensity toward toner starvation and the developed image defects resulting from such starvation.
