PROBLEM TO BE SOLVED: To provide a conveyance member which prevents an object from stagnating in a conveyance path at an appropriate location when the object is conveyed with a spiral blade having a discontinuous part, and a developing apparatus and an image forming apparatus.SOLUTION: A region &bgr; is formed for one pitch, upstream of a cleaning member 47. A region γ is formed from the downstream of the cleaning member 47 to the upstream of a transfer member 48, and includes a region γ1 on the side of the transfer member 48 and a region γ2 on the side of the cleaning member 47. Spiral blades arranged in the region &bgr; and the region γ have no discontinuous part FR. Developer conveyed in the region &bgr; and the region γ is unlikely to stagnate as compared with a case of including the discontinuous part FR. The spiral blade arranged in the region γ1 is a single blade, which conveys developer with a weaker force than the case where a plurality of blades, such as a double blade, are provided. The developer is unlikely to stagnate when transferred to a developer supply/conveyance member in the transfer member 48. |
