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.
