(2) Process of first transfer (Refer to Fig.3-19.)
1) OPC belt that has been through the development process rotates as contacting and
synchronizing with the transfer belt and drum.
2) OPC belt has been biased to the potential of -CBV(V). Potential of the transfer belt is
nearly GND.
3) Toner on the OPC belt is moved onto the transfer belt due to the difference of
potential between the OPC belt and transfer belt.
4) Toner that has been developed by each color is moved from the OPC belt onto the
transfer belt, and two color toner image is overlapped on the transfer belt.
5) Upon completion of the first transfer process, the toner image is transferred onto a
paper in the process of paper transfer.
