ABSTRACT:
An electric charging apparatus charges a surface of a charging object. The electric charging apparatus includes an electric field forming device including two electrodes facing each other that form an electric field therebetween. An electron discharging member is provided at a portion of one of the two electrodes that faces the other electrode and discharges electrons into the electric field. The electric charging apparatus also includes a voltage applying controller that controls a voltage applied to the two electrodes. The voltage applying controller selects two or more nonzero intensities of the electric field.
