3. Determination of developing bias (Vdc)
Developing bias is determined by adding the Vback value (based on the environment table)
to VL (bright area potential) determined in the foregoing control.
Developing bias (Vdc) = VL+Vback
VL: measured bright area potential determined by the potential control
Vback: the potential to remove foggy image that was determined in the environment
