(4) Transfer
The image developed by toner on the drum
A
is transferred onto the paper because of the electrical
attraction between the toner itself and the transfer roller
B
. The transfer roller is negatively biased
so that the positively charged toner is attracted onto the paper while it is pinched by the drum and
the transfer roller.
Figure 4-1-9 Transfer
The nominal transfer bias is set to approximately -1.8 kV (limit) with the -6 µ A current. Since the
ideal potential of the transfer bias depends on the thickness of paper, the bias is raised to approximately
-2.5 kV/-6 µ A for thicker paper. On the other hand, the bias current is reduced to -1.8 kV/-6 µ A for
thin paper.
