Abstract
An apparatus for controlling a flow of developer material in a development station. Gating means for regulating the flow of developer material in a development station are mounted for movement between an open position, allowing a flow of developer material and a closed position inhibiting the flow. An abutment, movable with the gating means, has a pair of opposed surfaces and contacts a limiting surface when the gating means is in the open position. A crank is drivingly connected to a drive means. The crank has a portion which engages one of the opposed surfaces when the drive mechanism moves the crank in one direction. This causes the gating means to move toward the open position. The crank engages the other opposed surface when the drive means moves the crank in an opposite direction. This causes the gating device to move to the closed position.
