The gears of the development unit are driven by the development drive gear
[A] when the development motor [B] (dc servomotor) turns.
The gears of the toner hopper are driven by the toner supply roller drive gear
[C] when the toner supply clutch [D] activates.
The above gears are helical gears. Helical gears are more quiet than normal
gears. The teeth of the development drive gear are chamfered so that they
smoothly engage with the development roller gear [E] when the unit is
installed.
