Developing Roller Drive

The developing roller consists of the inner pole magnet and the sleeve. The

magroll motor drives the inner pole magnet; the sleeve motor drives the

sleeve. The magroll motor also drives the agitation roller via the inner pole

When the toner density sensor detects low toner density, or the controller

asserts a "request for toner supply" engine operation command, the toner

supply clutch is activated, which drives the toner supply roller, the inner pole

magnet, and the agitation roller.
