Step 2 Scanning exposure
When the laser beam scans the drum surface, it causes the charge to be neutralized in the areas
struck by the laser beam. These areas on the drum surface form the electrostatic latent image.
2. Development stage
Particles of toner are placed onto the electrostatic latent image on the surface of the drum to
create a visible image. This printer uses the toner projection development method with a single-
component toner.
Step 3 Development
Note: Charges on the exposed area of the photosensitive drum are shown as positive in this
figure. In actuality they are negative, but they are more positive than those on the
developing cylinder.
