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.

Abstract: An image forming apparatus includes an image forming portion configured to form a toner image on a recording material, a fixing portion configured to fix the toner image on the recording material, a stacking portion configured to stack the recording material on which the toner image is fixed, an air passageway provided between the image forming portion and the fixing portion and between the image forming portion and the stacking portion, and an air blowing portion configured to blow air to the air passageway from outside of the image forming apparatus. The air passageway is configured so that the air blown from the outside by the blowing portion passes below the stacking portion and, thereafter, is folded back below the fixing portion and, then, passes again below the stacking portion.
