During development function, magnetic developer flows from the sump through the outlet to the magnetic transport means. A magnetic gate is normally located away from the outlet during the development function and is arranged to be swung into a position adjacent to the opening to magnetically stop the flow of developer through the outlet when it is desired to purge the development system.</p> |
