Developer Unit
The developer unit consists of the Magnet Roller, Sleeve and 2 Toner Auger.
The Toner Auger A transfers the developer to the front direction, and the Auger B transfers to the rear
direction to circulate the developer for mixing. The Toner Auger A also transfers the developer to the
Sleeve. The developer on the sleeve forms a brush by the magnetic force of the Magnetic Roller, and
makes contact with the electrostatic latent image on the drum. Toner is attracted to the areas of the
drum which have been discharged by the laser. The Doctor Blade regulates the height of the magnetic
brush which is formed by the developer which is attracted to the sleeve of the Magnetic Roller.
The system uses

developing method to mix the carrier to the
Toner. When the Toner is supplied, the Carrier is also supplied a little at the time. When the Carrier is
increased over the Constant value, the unnecessary Carrier is transferred together with the Toner by
the Auger A to the Toner Waste Container. As a result, it realizes the stable developing without
maintenance, without replacing the developer for a long time.
The TDC sensor is located near the Auger B to measure the ratio of toner to developer. The Toner
Density Control (TDC) is linked with Image Density detection, and Image dot count to stabilize the
Color Image Quality.
