Developing System
The machine employs the single-component, non-contact developing system.
In the non-contact, single-component developing system, the magnetic brush does not rub
the surface of the Photo Conductor (or the image). This prevents a foggy image from
occurring and the Photo Conductor from being worn.

Developing Roller
Toner Cartridge Rack (Carousel)
The Toner Cartridge Rack is mounted with four Toner Cartridges. The rack employs a
rotary system.
Development of the image of each color of toner is performed by rotating the Toner
Cartridge Rack.
