A charging device includes a substantially cylindrical charging electrode formed by rolling a flexible, semiconductive film, an electrode support member inserted in the substantially cylindrical charging electrode to support the charging electrode so as to be in contact with the turning surface of a charge acceptor, and a voltage applying means for applying a charging voltage to the charging electrode. The electrode support member is held with a gap between the electrode support member and the charge acceptor so that the charging electrode can be turned by an electrostatic force acting between the charging electrode and the charge acceptor. When a charging voltage is applied to the charging electrode, the charging electrode is pulled toward the charge acceptor by an electrostatic force acting between the charging electrode and the charge acceptor. Since the charging electrode is pulled for turning by the charge acceptor, the discharge region in which an appropriate gap is formed is expanded, whereby the charge acceptor can be satisfactorily charged in a stable potential distribution. The charging device may be provided with an electrode stabilizing member in contact with the charging member to stabilize the turning motion of the charging electrode and to hold the charging electrode in stable contact with the charge acceptor.
