Variation of OPC Belt Potential (See Fig.4-10.)
i) The OPC belt is initially biased to -CBV(V).
ii) The OPC belt surface is evenly charged to V
0
(V) in the charging process.
iii) The potential of the exposure part of the OPC belt is reduced to -VR(V) as it is
exposed to the laser beam in the process of exposing, and an electrostatic
latent image is formed on the OPC belt as the result.
iv) Negatively charged toner is moved onto the exposed part of the OPC belt in the
development process due to the difference of potential between -VR(V) (the
latent image) and -DBV(V), and a visible toner image is formed as the result.
v) Negatively charged toner on the OPC belt moves to the transfer drum surface
in the transfer process because the GND potential of the transfer drum is
greater than -VR(V) of the OPC belt.
vi) The OPC belt is discharged by the erase lamp.
