PURPOSE:To prevent a damage to a drum due to the direct rubbing of the front end of a developer receiver against the surface of the drum by providing the receiving member which is wired at slight distance from the drum and rocks as the drum rotates, and a magnet arranged under it. CONSTITUTION:A toner receiving member 5 which is rotatable around a fulcrum pin 4 and rocks as shown by an arrow according to the rotation of the photosensitive drum 1 is slanted, and a developer accumulated thereupon falls to a helical coil 7 under it. There is a slight gap between the receiving member 5 and drum 1, so part of the developer falls through this gap. The developer attracted by a magnet 6 is accumulated to fill the gap between the magnet 6 and drum 1, and then the deverloper is accumulated between the back side of the receiving member 5 and a partition wall. The developer moves toward the helical coil 7 through the rocking of the receiving member 5 and the helical coil 7 rotates counterclockwise, so the developer is collected in one direction and recovered. |
