装置。One image is formed by circulating a drum-shaped or endless belt-shaped photoreceptor a few times (both times), and the same charger serves both as a charger for charging the photoreceptor and a charger for transferring the developed image. In a copying machine, a charger is provided with a corona wire and another wire located between the corona wire and the photoreceptor, and at least two of the other wires are provided for each corona wire, and two other wires are provided for each corona wire. A corona wire is arranged between the wires, the other wire is electrically ungrounded when the photoreceptor is charged, and the other wire is grounded during transfer to change the width of the electron beam. A charging device for a copying machine characterized by:
