Abstract
A magnetic brush development system for developing latent electrostatic images carried by a photoconductor has a stationary section containing at least one development roll and a movable section containing at least a sump for storing a supply of developer. The movable section is translatable forwardly and rearwardly toward and away from the stationary section and includes a flow gate for selectively interrupting the flow of developer from the sump. There is a catch mechanism for releasably latching the sections of the housing which is interlocked with the flow gate to insure that the flow gate is closed before the catch is disengaged, while still permitting the flow gate to be opened and closed at will while the catch is engaged.
