A Scorotron transfer charger (59) has a corona wire (79) for generating electrical charges, while a grid (103) controls the amount of charge carriers which are ejected in the direction of a recording sheet. The Scorotron transfer charger (59) is arranged in such a manner that its grid is arranged approximately perpendicularly at a short distance above the photosensitive drum (51). As a result, neither paper dust nor toner particles can fall into the transfer charger (59). <IMAGE>
