Abstract:
1. A developing device, comprising: a developing member (1) that includes a scooping pole generating magnetic lines of force to scoop up a developer, (2) that rotates while holding the developer scooped up by the scooping pole on a surface thereof, and (3) that supplies the developer to an image holding body on which an electrostatic latent image is formed to develop the electrostatic latent image; and an agitation transport unit (1) that is disposed at a position where a developer used for development that has separated and fallen from the developing member is received, (2) that rotates about a center rotating shaft extending along a direction parallel to a rotating shaft of the developing member, (3) that agitates the developer, and (4) that transports the agitated developer to a scoop position where the developer is scooped up by the scooping pole, wherein a majority of the scooping pole is disposed on a downstream side of a line that connects the rotating shaft of the developing member with the rotating shaft of the agitation transport unit, in a rotation direction of the developing member when seen in a rotation axis direction of the developing member, wherein the line intersects the scooping pole, and wherein the scooping pole is disposed lower than a separation pole of the developing member in a gravity direction.
