DEVELOPING BIAS
The developing bias voltage (Vdc) is applied to the Developing Roller so
that an adequate amount of toner is attracted onto the surface of the PC
Drum.
During development, Vdc of DC(-) + is applied so that Toner can be
attracted PC Drum easily. This component of AC is applied only during
development. Other than during development, only Vdc of DC(-) is
applied.
The developing bias (Vdc) is supplied from High Voltage Unit (HV1).
