PURPOSE:To prevent a toner from scattering, to prevent lowering in life of a photosensitive body, and to make a device compact by providing a toner stirring means for stirring up a residual magnetic toner on the photosensitive body by magnetic force. CONSTITUTION:In a two rotation and one copying system, a toner stirring mechanism 15 consisting of a magnet 13 and a magnet fixing plate 12 is provided on the inside of a photosensitive body 1, and the magnet 13 is supported by holding a small gap on the rear side of the photosensitive body 1 in the axial longitudinal direction. As for an untransferred toner image after the transfer, the magnetic toner is moved by relative movement of the photosensitive body 1 and the magnet 13, and the residual toner is removed completely by a developing and cleaning device. Accordingly, the toner is not scattered, and since the toner stirring member is contained in the inside of the photosensitive body, no influence is exerted on a service life of the photosensitive body, and the device can be made compact. |
