COPY PROCESS
3 - 10
6) 1st transfer
- 1st transfer is a process of transcribing the toner image (visible image) formed on the photocon-
ductive drum to the transfer belt. A positive bias is applied to the transfer roller, causing the trans-
fer belt to be positively charged. This in turn helps to form an electric field E between the transfer
belt (positive) and the photoconductive layer of the photoconductive drum (grounded), thus mak-
ing the toner image transferred to the transfer belt. In the copy process of this equipment, images
are transferred in the order of K→C→M→Y on the transfer belt.
