This copier uses a double roller development system and a dual component 
development process with toner particles 6.8 

µ

m and developer particles 50 

µ

m. To 

improve image quality, the width of the magnetic area on the lower development roller 
has been reduced. 
This system differs from single roller development systems in that: 

• 

It develops the image in a narrower area 

• 

It develops the image twice 

• 

The relative speed of each development roller against the drum is reduced. 

This machine contains a toner recycling system. Toner recycled from the drum 
cleaning unit is transferred to the toner hopper with fresh toner, where they are mixed 
by the toner agitator. The mechanism is explained in the Toner Supply and Recycling 
section.
