ABSTRACT:
Vacuum removal means for removing excessive developer material from a member having a latent magnetic image developed with magnetic developer material. The vacuum removal means comprises a chamber having entrance and exit ports of predetermined cross-sectional area such that the ratio of entrance port to exit port is sufficiently small to assure substantially uniform air flow across the entrance port when the chamber is subjected to negative pressure through the exit port. The entrance port of the chamber is in communication with means for subjecting the developed surface of the member to a substantially uniform shearing air flow when the chamber is subjected to the negative pressure. A second entrance port of equal cross-sectional area to the first entrance port may be provided to the chamber in association with gating means for selectively varying the cross-sectional area of each entrance port while maintaining a constant combined cross-sectional area for the entrance ports.
