4) Data writing

Data writing is a process of converting the image signals transmitted from the image processing

section into light signals and exposing the drum surface with the light signal.

Namely, the image signals transmitted from the image processing section are converted into optical

signals (laser emission) by the semiconductor laser element, which are then used to expose the

drum surface, thus forming an electrostatic latent image there.
