Sleeve/Magnet Roller
• The Sleeve/Magnet Roller, which consists of an outer sleeve roller and an inner magnet
roller, conveys developer to the point of development.
• The magnetic force of the magnet roller at the point of development is the strongest so
that the developer brush stands straight up to deliver the greatest amount of toner to the
point of development.
13-2.
Developing Bias
• A developing bias voltage (Vb) is applied to the Sleeve/Magnet Roller to prevent toner
from sticking to the background of the image.
• The amount of toner attracted onto the surface of the PC Drum depends on how much
lower the PC Drum surface potential (Vi) is than Vb (i.e., potential difference).
✽
When the potential difference is large, a greater amount of toner is attracted.
✽
When the potential difference is small, a smaller amount of toner is attracted.
