PURPOSE:To simplify a driving mechanism and also to prevent damage of the surface of a photoreceptor, by utilizing an attraction/repulsion operation of a magnet member for a driving mechanism of a sealing device. CONSTITUTION:The driving mechanism C is formed by the magnet member 10 provided on a blade 8 of the sealing device B and a driving magnet member 11 provided on a position for generating an attraction/repulsion magnetic field with the magnet member 10. This driving magnet member 11 consists of a pair of the magnet members 13a, 13b having each opposite polarity. In this state, when the driving member 11 is rotated, the attraction/repulsion operation is generated in the driving mechanism C. As a result, the blade 8 is rotated, and a plate-like collecting member 4 is made to press-contact and is separated to and from the surface of the photoreceptor 1. In this way, transfer of pressure force to the surface of the photoreceptor can be executed by non-contact, therefore, damage of the surface of the photoreceptor is prevented and also the driving mechanism can be simplified. |
