Filed: 1989-08-31
Abstract: PURPOSE:To prevent a developer from falling from a recycle means on a developer staying area and to inhibit the developer from depositing on a straightening plate by cutting part of the straightening plate at the part where the developer is controlled by a partitioning plate not to flow. CONSTITUTION:The part of the straightening plate 4 which does not correspond to the flow part of the developer controlled by the partitioning plate 8 not to flow is cut to form a nearly triangular cut part 10. Consequently, when the developer which is collected by a cleaning device falls from a recycle conveyor 5, it falls directly on an agitator roller 6 positioned below at the part corresponding to the cut part 10 of the straightening plate 1 and drips only on the flow part of the developer on the straightening plate 4 at the same time. Therefore, the developer falls uniformly without depositing at any specific part of the straightening plate 4.
