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.
