1.3.2 Exposure
In the "Exposure" process, the negatively charged drum surface is scanned by a laser beam and an
invisible electrostatic latent image is formed on the drum surface.
The laser beam is radiated from a laser diode inside the ROS ASSY and scans the drum
surface from end to end in the shaft direction via a polygon mirror, fixed mirror and the
Scanner Assy lens inside ROS ASSY. One laser beam is output from the laser diode.
