7-3. Developing Bias
A negative voltage (Vb = Developing Bias voltage) is applied to the Sleeve Roller
to prevent a foggy background on the copy. The amount of toner attracted onto the
surface of the PC Drum depends on how much lower the PC Drum surface potential
(Vi) is than Vb (i.e., the potential difference).
D When the potential difference is large, a greater amount of toner is attracted.
D When the potential difference is small, a smaller amount of toner is attracted.
Because the Magnet Roller of this copier is movable, a flat spring is used as the Bias
Terminal which follows the movement of the Magnet Roller.
