2.1.3.4 (4) First Transfer (Drum
In the first transfer step, the toner image formed on the drum surface is
transferred onto the belt (Transfer Assembly) by the 1st BTR (First Bias
Transfer Roll).
o The 1st BTR is a conductive roll, receiving positive high voltage
from the HVPS. The 1st BTR touches the back of the belt. Following
the rotation of the belt, the 1st BTR gives a positive charge to the
back of the belt. The toner image on the drum surface (negatively
charged) is attracted to the positive charge on the back of the belt.
The image is transferred from the drum surface to the belt.
