Abstract
An arrangement for moving a developer material along the developer axis where a bulk of the developer material is stored in a reservoir located on one side of the developer. The developer consists of the reservoir and a housing having a cavity extending along the developer axis. Several angled ribs are formed inside the cavity. A magnetically transparent sleeve resides inside the cavity and is rotated about the axis. Finally a magnetic element placed inside the sleeve magnetically attracts the developer material toward the sleeve such that the rotation of the sleeve induces the rotation in the developer material. As the developer material comes into contact with the angled ribs, the rotation of the developer material is translated into a lateral motion along the axis by the angled ribs.
