PCDU (Photo Conductor and Development Unit)
7.7.3 MECHANISM (DEVELOPMENT)
Development System
A dry two-component magnetic brush development system is used.
The dry two-component magnetic brush development system gives a suitable electrostatic charge to the toner using magnetic particles called carriers which form a magnetic brush due to their magnetism, and cause toner to adhere electrostatically to the drum surface.
Agitation System
This device uses a double-coil agitation system (twin-shaft environment development system). Toner transported from the toner cartridge to the development unit will be agitated with the developer by two toner transport coils [A] and will be delivered to the development roller.
The amount of developer adhering to the development roller is controlled by a doctor blade [B], and supplies toner to the surface of the photoconductor unit.
