PURPOSE:To prevent pollution due to a developer and prevent film forming of an image carrier by arranging an oscillating member between a recovering blade and a carrying member so that this oscillating member is rotated and shaked there. CONSTITUTION:A helical oscillating member 35 like a coil spring which is rotated and shaked around a rotating shaft 34 is arranged between a recovering blade 31 and an auger 33. A gear 38 of the rotating shaft 34 is driven by a gear 37, which is attached to a rotating shaft 36 of the auger 33 on the outside of a casing 29, to rotate and shake this oscillating member 35. The end part of the oscillating member 35 has a diameter slightly smaller than that of the rotating shaft 34 to prevent slip between the rotating shaft 34 and the oscillating member 35 at a normal rotation time. Thus, the oscillating member 35 is rotated shaked, and oscillated repeatedly by rotation of the auger 33 to break a toner T, which is peeled from the surface of a photosensitive body 17 by a main blade 30 and is recovered and accumulated by the recovering blade 31, and carries this toner T to the auger 33 successively. |
