ABSTRACT:
A toning station having an applicator with a rotatable component and a mixing device directly below it in a chamber are both rotated to tone an electrostatic image. To not tone an electrostatic image that is passing the applicator, the mixing device is not rotated while the rotatable component of the applicator is rotated for a short period of time to clear a developer position adjacent the electrostatic image of developer. A supply of developer in the chamber has a low enough level that when the mixing device is not rotating it does not come under the magnetic influence of the applicator but when the mixing device is rotating it is within such influence.
