3 Controlling the Developing Bias
3.1 Outline
A DC bias and an AC bias are applied to the developing cylinder, and the developing
bias control system has the following functions:
[1] turning on and off the bias.
[2] controlling the developing DC bias to a constant voltage level.
[3] controlling the developing AC bias to a constant voltage level.
[4] controlling the voltage level of the developing bias.
The system used to control the developing bias control mechanism is constructed as fol-
