Driven by the development motor
A separate motor, dedicated to the task, drives the development roller.
This reduces the load on the drum motor to stabilize drum motor rotation.
The development motor drives the three mechanisms indicated on the slide.
The toner supply clutch transfers motor power to the toner supply unit at the
appropriate time. This is determined by the toner supply control processes,
which are described later.
