2.4
Drum Unit
2.4.1 Photosensitive drum
Generates the latent electrostatic image and develops the image on the drum surface.
2.4.2 Primary charger
Forms a uniform charge on the drum surface.
(1) Corona
wire
Generates the ion charge on the drum.
(2) Grid
Spreads the ion charge evenly over the drum surface.
2.4.3 Transfer roller
Transfers the toner image to the paper from the drum surface.
2.4.4 Cleaner
Removes the paper dust or dirt on the surface of the photosensitive drum.
2.5
Toner Cartridge
Develops the electrostatic latent image on the photosensitive drum with toner and forms the
visible image.
