OD (One-way circulation of Developer) system [A]
The developer supply/recovery route is divided to make the toner density uniform in the longitudinal direction of the unit and stabilize the solid image.
The amount of developer adhering to the development roller is controlled by a doctor blade [B] and supplies toner to the surface of the OPC drum.
Double-coil Agitation System (Twin-shaft Environment Development System) [A]
Toner transported from the toner bottle to the development unit will be agitated with the developer by two toner supply 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 OPC drum.
