摘要：
A toning station particularly usable in a multicolor image-forming apparatus includes an applicator and a developer mixing mechanism. A transport roller with a fluted surface transports developer from the mixing device to the applicator. A magnetic gate is positioned inside the transport roller and has a first position in which it attracts developer from the mixing device to the transport roller to facilitate delivery of developer to the applicator. The magnetic gate is movable to a position opposite the applicator where it inhibits passage of developer to the applicator to stop the development action of the station.
