(5) Transfer
A sheet of paper is placed over the OPC drum surface, and an electric charge is
given to the paper from its backside 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.
