摘要：
A developing device includes a housing containing a developer, a developer carrier, a developer conveying path, a developer conveying member, and a plurality of paddle members. The developer conveying path includes a first conveying path and a second conveying path. The developer conveying member is disposed in the second conveying path and includes a rotating shaft and spiral blades formed around the rotating shaft. The developer conveying member is rotationally driven to convey the developer in the second direction and feeds the developer to the developer carrier. The plurality of paddle members project in a radial direction from the rotating shaft of the developer conveying member at one circumferential position on the rotating shaft. The plurality of paddle members is contiguously arranged in the axial direction of the rotating shaft to connect the spiral blades adjacent to each other in the axial direction.
