6. TONER DENSITY DETECTION AND TONER SUPPLY

6.1 TONER SUPPLY

The toner supply drive gear [A] turns when the development motor is on. The toner supply
clutch [B] applies the rotation from the toner supply drive gear to the toner supply roller gear
[C], which drives the agitator gear [D]. Toner catches in the grooves on the toner supply
roller [E]. Then, as the grooves turn past the opening, the toner drops into the development
unit.
The teeth on both the toner supply drive gear and the toner supply roller gear are chamfered.
