ABSTRACT:
An image forming apparatus has a magnetic brush toning station for applying toner to an electrostatic image. The brush includes a rotatable magnetic core positioned inside a non-magnetic sleeve. To facilitate the removal of developer from the sleeve after it has toned an electrostatic image, a skive located against the sleeve downstream of the toning position has a roughened surface upon which the developer rolls or tumbles to move away from the sleeve and ultimately fall into a mixing sump.
