Abstract
A magnetic brush development system for developing latent electrostatic images carried by a photoconductively coated substrate has a split housing comprising a movable section with a sump for storing a supply of developer, a stationary section including one or more development rolls which are fed with developer from the sump to carry out the development process, a latching mechanism for releasably securing the movable section of the housing to the stationary section, and a flow gate which is interlocked with the latching mechanism so that the flow gate is closed to interrupt the flow of developer from the sump whenever the latch is released.
