Abstract
A developer transporting device includes a first transport passage through which a developer is transported in a first direction along a direction oriented downwardly in a direction of gravity, and a second transport passage which communicates with the first transport passage on a downstream side of the first transport passage and through which the developer is transported in a second direction along a direction oriented upwardly. The first transport passage is provided with a first transport force generating member which generates a transport force for transporting the developer in the first direction, and the second transport passage is provided with a second transport force generating member which generates a transport force for transporting the developer in the second direction.
