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:
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 the Image-formation
process graphic and are described in the following sections.
