Functional block Steps Description
Latent image formation 1. Pre-exposure
2. Primary charging
3. Laser-beam exposure
An invisible latent image forms on the
surface of the photosensitive drums.
Development 4. Development Toner adheres to the electrostatic latent
image on the photosensitive drums.
Transfer 5. Primary transfer
6. Secondary transfer
7. Separation
The toner image transfers to the ITB and
later to the paper.
Fusing 8. Fusing The toner fuses to the paper to make a
permanent image.
