The ID sensor and TD sensor control toner density. The output of these two
sensors determines when to switch the toner supply clutch [A] on. The clutch
transfers drive from the development motor to the toner supply mechanism.
When the toner supply clutch turns on, the agitator [B] mixes the toner in the
hopper and sends it to the toner supply roller [C].
Toner is caught in the grooves in the toner supply roller. Then, as the grooves turn
past the opening, the toner falls into the development unit.
