4. Transfer
A sheet of paper is placed over the OPC drum surface, and an electric charge is given to the
paper from its back side by the transfer roller.
When a high voltage is applied to the transfer roller from the power source, the charge induced
on the transfer roller moves on to the surface of the paper through the contact part between
the transfer roller and the paper, the toner being attracted to the paper surface from the OPC
drum surface.

5. Drum cleaning
Unfixed toner remaining on the OPC drum is removed by the drum cleaning blade and
collected into the waste toner area of the toner cartridge.
