An electrophotographic printer includes a photosensitive drum, a developing unit, an image transfer unit, and pre-transfer discharges arranged between the developing unit and the image transfer unit. The pre-transfer discharging means is arranged to progressively reduce the absolute value of the electric potential of a given point in the surface of the photosensitive drum. The reduction of the electric potential is performed in a non-abrupt manner through two or more steps as the given point is moved from the developing unit to the image transfer unit.
