The toner supply motor [A] supplies toner in the development unit that is at the
development position via gears that are behind the supply auger [B].
Toner is fed forward as the toner bottle rotates, and it falls into the toner supply
section [C]. The supply auger [B] transfers the toner in the toner supply section [C]
to the development unit [D].
The development shutter [E] in the development unit closes under its own weight
when the revolver rotates, preventing toner backflow.
For more details on toner supply, see Toner Supply Control earlier in this section.
