Developing Assembly
Outline
The developing assembly mainly consists of the developing cylinder, developing blade, toner agitation plate, and toner feed screw, and driven by the main motor (M1) and developing cylinder clutch (CL1).
The toner supplied from the toner cartridge is fed into the drum unit by the toner feed screw and toner agitation plate. The toner presence/absence in the drum unit is detected by the developing assembly toner sensor (S25) which is a magnetic permeability sensor.
