Image-formation system
Laser printing requires the interaction of several different technologies, including electronics, optics, and
electrophotographics, to provide a printed page.

Each process functions independently and must be coordinated with the other device processes. Image
formation consists of the following five processes:
●
Electrostatic latent-image formation
●
Developing
●
Transfer
●
Fusing
●
Drum cleaning
The five processes contain eight steps, which are shown in the figure
Figure 4-11 Image-formation
system on page 64 and described in the following sections.
