Abstract: 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.
