1)Construction of the Toner Cartridge
•
The developer unit consists of the magnet roller, agitator 1 and agitator 2.
•
Toner is mixed by the agitator 1 and 2, then transported onto the developer sleeve.
Toner on the developer sleeve adheres to the electrostatic latent image on the
drum by AC bias for development.
•
The developer blade charges toner and controls the thickness of toner on the
sleeve.
•
The toner level sensor is placed under the toner cartridge to detect the toner level.
•
The developing performance is enhanced by using mono-component toner.
•
The developing unit also contains the recycling system. Toner is collected and
sent to the waste toner box.
