After the image is transferred onto paper, any remaining toner on the PC drum is
scraped off by the cleaning blade and collected in the used toner bottle.

Image transfer is the process of transferring the toner image created on the PC
drum during the developing process to the paper. This printer uses the roller
image transfer method, instead of corona image transfer, as the image transfer
process. In roller image transfer, there is no generation of ozone as there is with
corona discharge. Also, there is no blurring caused by motion in the image
transfer, because the image transfer roller is maintained for the pressure bonding
of the paper with the PC drum.
A reverse bias voltage is applied so that the positive toner is not transferred onto
the image transfer roller. (The drum charge bias voltage is used.)
