Image-formation process
The image-formation process consists of seven steps divided into five functional blocks:
●
Latent-image-formation system
◦
Step 1: Primary charging
◦
Step 2: Laser-beam exposure
●
Developing system
◦
Step 3: Developing
●
Transfer system
◦
Step 4: Transfer
◦
Step 5: Separation
●
Fuser system
◦
Step 6: Fusing
●
Drum cleaning
◦
Step 7: Drum cleaning

Latent-image formation block
During the two steps that comprise this block, an invisible latent image is formed on the photosensitive
drum.
Step 1: Primary charging
To prepare for latent-image formation, the surface of the photosensitive drum is charged with a uniform
negative potential. The primary charging roller charges the photosensitive drum directly. The primary
