b-2) Laser beam exposure
Figure 3-21 Laser Beam Exposure
When the laser beam scans the drum surface, it causes the charges in the areas struck by
the laser beam to be neutralized. These areas on the drum surface form the electrostatic
latent image.
c) Developing block
Particles of toner are placed onto the electrostatic latent image on the surface of the drum to
form a visible image. This fax uses the toner projection development method with a single-
component toner.

NOTE
Charges in the exposed areas of the photosensitive drum are shown as
positive in this figure, even though they are actually negative. It means that
the photosensitive drum potential is higher as compared with that of cylinder.
