Image Transfer

(1) Overview
• Image transfer is the process of transferring the toner image created on the PC Drum in the devel-
oping process to paper.
• Roller image transfer is used instead of corona image transfer as the image transfer method.
• In roller image transfer, there is little generation of ozone due to corona discharge. Also, there is
no blur of toner because the paper is always pressed by the PC Drum and the Image Transfer
Roller.
• When cleaning the Image Transfer Roller and before printing, reverse bias is applied.
• The residual electric potential on the paper is dissipated via a discharge needle.
