Abstract
A voltage application timing control unit is connected to a DC component applying unit and an AC component applying unit in a developing bias applying unit. The voltage application timing control unit independently controls the DC component applying unit and the AC component applying unit so as to independently control the timing of applying a DC voltage from the DC component applying unit to the related member and the timing of applying an AC voltage from the AC component applying unit to the same.
