The dimensions of the laser beam are as shown in Figure 2-1-6.
Figure 2-1-6
Scanning in the main direction is provided by the rotating polygon mirror, while scanning in the auxiliary direction is pro-
vided by the rotating drum, forming a static latent image on the drum.
The static latent image of the letter “A”, for example, is formed on the drum surface as shown in Figure 2-1-7. Electrical
charge is dissipated on the area of the drum surface irradiated by the laser.
The focal point of the laser beam is moved line by line, and adjacent lines slightly overlap each other.
