(Image exposure: Area exposed by laser isthe image area)Developing block 4 Development Negatively charged toner on the Developing Roller is transferredand attached onto the Photosensitive Drum with contact develop-ment method.Transfer block 5 Transfer Toner on the surface of the Photosensitive Drum is transferred to apaper by applying positive charge to the Transfer Roller.6 Separation With the curvature separation method, the paper is separated fromthe Photosensitive Drum. In the case of thin paper which has lowelastic force, the Static Eliminator reduces the electric charge onthe back side of paper to make the thin paper to be separated easily.Fixing block 7 Fixing Toner on the paper is fixed on the paper using heat and pressure.Cleaning block 8 Drum cleaning Residual toner on the Primary Transfer Roller and Transfer Rolleris transferred to the Photosensitive Drum, and the Developing Roll-er collects the residual roller on the Photosensitive Drum into theDeveloper.Cartridgeâ– Functional ConfigurationThe cartridges have the function to form a visible image on the Photosensitive Drum with toner.The cartridge on this machine is Drum separated type Cartridge. The Toner Cartridge and the Drum Cartridge are combined tooperate as one such as conventional integral type cartridge structures.The Toner Cartridge is composed of the Toner and the Developer and the Drum Cartridge is composed of the PhotosensitiveDrum and the Primary Charging Roller.The DC Controller drives the Main Motor (M2) to rotate the Photosensitive Drum and the Developing Roller The Primary ChargingRoller rotates by following the Photosensitive Drum rotation.2.
