Abstract
A toning apparatus for an electrophotographic marking engine using multi-component developer includes a magnet for producing a magnetic field through the surface of a toning member, so that carrier particles in the developer in a receiving zone are attracted to the toning member. A rotatable ribbon blender includes an axle, a first inner ribbon and a first outer ribbon having opposite handednesses of twist and arranged to rotate with the axle, and a paddle connected to the first outer ribbon. The ribbon blender is disposed at least partially in the developer in a sump, so that when the ribbon blender rotates, the paddle transports developer from the sump to the receiving zone. No feed roller or supply roller is required; the ribbon blender mixes and transports developer.
