Abstract
An improved development system for an electrophotographic system includes a reload defect detector for generating a signal corresponding to a potential for reload defect detected in an image to be developed by an electrophotographic system; and a magnetic roll speed selector for selecting a rotational speed for a magnetic roll in a development system of the electrophotographic system, the selected rotational speed corresponding to the generated reload defect potential signal. The speed of the magnetic roll is selected to be a lower speed in response to the potential for reload defect being relatively low. The slower rotation of the magnetic roll prolongs the life of the developer and extends the operational life of the development system before corrective action is needed.
