Abstract
A development station conveys developer material from a sump to a magnetic brush for development of latent images on a photoconductor. The developer material flows through a slot adjacent the magnetic brush. A thin film having a plurality of apertures is positioned adjacent the slot. The film is movable to align the apertures with the slot so that developer material can pass through the slot to the brush. Movement of the film perforations out of alignment with the slot shuts off the flow of developer material to the magnetic brush.
