Claim Text:
1. A replaceable unit for an electrophotographic image forming device, comprising: a housing having a reservoir for storing toner; a rotatable shaft positioned within the reservoir and having an axis of rotation; a first magnet and a second magnet connected to the rotatable shaft and rotatable around the axis of rotation in response to rotation of the rotatable shaft, the first magnet and the second magnet passing near at least a portion of an inner wall of the housing forming the reservoir during rotation of the first and second magnets, wherein an amount of angular offset between the first magnet and the second magnet varies depending on an amount of toner in the reservoir; and a first linkage rotatable with the rotatable shaft and rotatable independent of the rotatable shaft between a forward rotational stop and a rearward rotational stop, the second magnet mounted on the first linkage, the second magnet is spaced angularly rearward relative to an operative rotational direction of the rotatable shaft from the first magnet when the first linkage is at the forward rotational stop.
