13.2.3. Exposing
When the drum which is charged with the fixed electric charge is irradiated by the laser beam, the plus charge and minus charge
are generated at the Charge Generation Transfer Layer. Passing through the Charge Generation Transfer Layer which conducts
the minus charge, the plus-charged drum's surface is neutralized to be skipped. Then the plus charge goes to the ground from the
electric conductive cylinder. Consequently the charge of the part which is not exposed remains as it is, and the electric potential of
the scanned part changes.
At that time an invisible image is created on the drum.
