Abstract

This invention relates to an electrostatic charger and discharger which can realize ozone-less, non-contact charging that can prevent the member to be charged or the member to be charge-removed from deteriorating upon irradiation of an electromagnetic wave. Each of the charger and discharger has an electric field forming system with a specific structure for efficiently forming an electric field that causes ions produced by an electromagnetic wave to become attached to the major surface of the member to be charged or the member to be charge-removed in a space.
