(1) Drum unit
The tandem development system uses four drum units which are isomorphic to each other, in cyan, magenta, yellow, and
black colors. In the drum unit, the main charger disperses charging potential over the drum to evenly charge the drum.
When the light emitted by LED hits the charged drum, the electrostatic latent image is developed on the drum. The electro-
static latent image is "developed" by toner applied by the developer unit and transferred onto the primary transfer belt in
four colors. The toner remaining on the drum is scraped off by the cleaning blade and driven outside by the spiral screw.
The residual potential on the drum is discharged by the exposure to the eraser lamp. Thus, the drum becomes ready for
the next main charging.
