4.3.1 Toner flow

1. Toner stored in the toner cartridge is agitated by the agitating blade and conveyed onto the front side of the toner cartridge by the toner
supply screw.
2. Toner conveyed onto the front side of the toner cartridge is conveyed through the toner collecting port and then conveyed to the imaging
unit collecting port.
3. The toner conveyed to the collecting port is conveyed into the toner chamber by the conveyance screw.

still available for use in the toner chamber.
5. Toner conveyed onto the rear side of the toner chamber is fed to the toner supply roller via the agitating screw.
6. Toner fed to the supply roller is conveyed onto the developing roller.
At this time, the regulator blade/1st and /2nd regulate the height of toner on the surface of the developing roller.
7. Toner on the developing roller is fed to the electrostatic latent image formed on the surface of the photo conductor.
8. Toner left on the developing roller is neutralized and returned to the supply roller.
9. The toner on the surface of the photo conductor is transferred onto the transfer belt.
10. Toner left on the surface of the photo conductor is scraped off by the cleaning blade.
