•
The amount of toner attracted onto the surface of the PC Drum is controlled by varying
the developing bias voltage.
•
As the PC Drum deteriorates and its photoconductive layer begins to wear, it becomes
more sensitive to the increase in the amount of toner. As a countermeasure against this
problem, the developing bias voltage is automatically switched according to the PC Drum
temperature, thereby stabilizing the image quality level.
