(2) Image forming process diagram
The operation of this section are composed of the six processes:
charging, exposure, development, transfer, separation, and discharg-
ing. An OPC drum is used as the photocoductor drum. Toner is of
one-component. For charging, the rotation brush is used. For trans-
fer, the roller is used and virtually no generation of ozone. It is also
compact. The high voltage required in this section is provided by the
high voltage power PWB.
