Image-formation process
Laser printing requires the interaction of several different technologies including electronics,
optics, and electrophotographics to produce a printed page. Each process functions
independently and must be coordinated with the other printer processes. Image formation
consists of the following five processes:
1 Latent-image formation
2 Developing
3 Image transfer
4 Fusing
5 Transfer-belt cleaning
The five processes are divided into twelve steps, which are shown in figure 28 and described in
the following sections.
