(2) First Transfer Process (Refer to Fig.4-18.)
i) The OPC belt has been through the development process and contacts and
synchronizes with the transfer drum.
ii) The OPC belt has been biased to the potential of -CBV(V). The potential of the
transfer drum is nearly GND.
iii) Toner on the OPC belt is moved onto the transfer drum due to the difference of
potential between the OPC belt and the transfer drum.
iv) Toner that has been developed by each color in sequence is moved from the
OPC belt onto the transfer drum and the color toner images overlap on the
transfer drum.
v) Upon completion of the drum transfer process, the complete toner image is
transferred onto paper in the paper transfer process.
