12. DEVELOPMENT SYSTEM
12.1 General Description
Development is the process of converting electrostatic latent images into visible images. The developer
material is supplied onto the photoconductive drum surface by the developer sleeve (magnet roller).
Then the toner in the developer material adheres to this drum surface to form images. This process is
performed in the developer unit.
This chapter explains about the units, parts and control circuits related to development.
The developer unit in this equipment has a recovered toner supply mechanism which recycles the
recovered toner scraped off by the drum cleaning blade. The developer unit is driven by the main motor
(M3) to rotate the mixers and the developer sleeve.
