Developing System

• Two types of Developing Systems are used, a non-contact developing system and an
alternating current application system.
1. A negative charge is applied to the Supply Roller and toner sticks to the Developer
Roller.
2. The toner is evened out by the 1st Regulator Blade.
3. A negative charge is applied to the 2nd Regulator Blade and the toner is negatively
charged.
4. Since an alternating current is applied to the Developer Roller, if there is negative ele-
ment, the toner sticks to the PC Drum. In addition, the image density is determined by
the time for the negative element.
