Toner Supply
The agitator [2] mixes toner and sends it to the development roller.
Development Unit
This machine uses a one-roller development system. The high voltage supply applies -700V to the
development roller.
When the user removes the developer seal, the developer falls and the magnetic reverse roller [7] mixes
the developer.
This machine does not use a TD sensor or ID sensor to control toner density. The pre-doctor blade [3] and
the doctor blade [6] control the toner density.
Toner Density Control
More toner is fed when the toner
coating on the development roller
is thin
Less toner is fed when the toner coating
on the development roller is thick
[A]: Pre-doctor blade
[B]: Doctor blade
[C]: Circulation of developer
