When a fine power (toner) that has a charge of the same polarity as the electrostatic latent image and
color black (or other color) comes near the electrostatic latent image formed on the drum surface, the
toner adheres to the image only by electrostatic force, causing the electrostatic latent image to be devel-
oped, resulting in a visible image being formed. This is the developing process performed in the devel-
oper unit.
