MAGNETIC INCREMENTAL CASCADE DEVELOPMENT SYSTEM

摘要

Electrographic recording device wherein development takes place at the recording station in such a manner that obscuring of the developed image by the developer unit is minimized. A developer trough or retaining structure constituting one part of the developing unit precedes the recording station. An oscillating magnet, forming another part of the developing unit and positioned adjacent the rear surface of the recording medium, effects movement of developer over latent electrostatic images printed upon the recording medium and its rapid return to the trough so that the developed image can be seen almost immediately.
