Abstract
Development stations are provided. A development station has a housing having a recirculation path an auger being rotatable to move the developer along at least part of the recirculation path. A drive transmission has a first output mechanically linked for movement with a first end of the auger and a second output mechanically linked for movement with a second end of the auger and distributes a force at an input end between a first force provided at the first output and at a second force provided at the second output to rotate the auger against a drag. The first force and the second force are less than a third force to drive an alternative auger from a driven end. The auger has a first end yield strength and a second end yield strength that are each less than a driven end yield strength of the alternative auger.
