1.The OPC belt is biased to the -CBV(V) by power supply CBV.

2.The OPC belt is then evenly charged to the negative high voltage by the OPC charging system. The charging system consists of a charging brush that is biased by power supply CHV and a discharge roller that is biased by power supply DCV.

3.The developer roller in the toner cartridge is biased to -DBV(V) by power supply DBV.

4.Frame potential of transfer drum is GND.
