Charging process (Step 1)

A negative high DC voltage is applied to the gold-plate tungsten wire of the charging corona which is provided
for each Y, M, C, and K photoconductor drums. Then the wire discharges toward the drum in order to charge
the entire drum surface with the negative electrostatic charge. The charge on the drum is uniformly distributed
on the drum surface with the charging control plate.

Laser exposure process (Step 2)

The material used for the drum surface has a characteristic that holds electrostatic charges in darkness and dis-
charges under light. This enables creating a electrostatic latent image on the drum with laser beam. The laser
beam draws the image shining on certain points on the drum where the text or image presents according to
color separation data (Y, M, C, K data) created on the image processing section.
