4.2.2.2 Variation of the OPC Belt's Potential
(see Fig. 4-10).
The OPC belt is biased to -CBV. The OPC belt's surface is evenly charged
to V in the process of charging. The potential of the OPC belt is dis-

image is formed on the OPC belt.
Negatively charged toner is attracted to the OPC belt in the development
process due to the difference of potential between -V
visible image is now formed.
Negatively charged toner on the OPC belt is moved to the transfer drum
in the transfer process because the potential GND of the transfer drum is
greater than -V
The OPC belt is discharged by the erase lamp shining on the OPC belt.
