The first illustration shows the relationship between the toner, the
-Vo(V) at the non-exposed area of the OPC belt and the -VR(V) at
the exposed area of the OPC belt.
3. Developing is processed by toner adhering to the OPC belt due
to the attraction between the toner and the -VR(V) at the
exposed area of OPC belt.
The toner image becomes visible on the OPC belt.
Note: No developing takes place on the non-exposed area
because the potential of toner and that of the OPC belt is an
identical pole and therefore, repels.
