PURPOSE:To facilitate the attachment and detachment of a cylindrical photosensitive body by means of the simple constitution and to securely transmit a rotational driving force. CONSTITUTION:When a pressurizing means 23 is moved by a can mechanism, the pressurizing arm part 23b of the pressurizing means 23 pressurizes and deforms O-rings 22, provided on a flange 20, so that they are projected. The parts of the O-rings 22 are caused to adhere to the inside wall of the cylindrical photosensitive body 1, thereby supporting the cylindrical photosensitive toady 1 by means of the flange 20 via the O-rings. In this condition, a rotational driving force is transmitted to the cylindrical photosensitive body 1 via a driving gear 3, a photosensitive driving shaft 21, the flange 20 and the O-rings 22. |
