2.8.4 Image Transfer
Image transfer is the process of transferring the toner image created on the Drum in the developing
process to paper. The Roller Image Transfer is used instead of the Corona Image Transfer as the image
transfer method. In the Roller Image Transfer method, there is little generation of ozone due to corona
discharge. Also, there is no blur of toner because the paper is always between the Drum and the Image
Transfer Roller.

2.8.5 Residual toner distribute
The residual toner must be removed from the drum. This step does not actually remove the residual toner
from the drum surface. Instead, a “Eraser brush” is used to evenly distribute the remaining toner over the
drum surface. When the drum surface is charged in preparation for printing the next document the
remaining toner is also charged. Any residual toner that is not exposed in the subsequent drum exposure
process is attached back onto the developing roller.
