摘要：
A feeding device for feeding a developer includes an accommodating member (71b), a first helical feeding member (87) including a first region having a first diameter and a second region having a second diameter smaller than the first diameter in a named order with respect to a first feeding direction (W), a second helical feeding member (88) for feeding the developer in a second feeding direction (X) crossing the first feeding direction, and a wall (72t) extending toward the second helical feeding member so that the wall is spaced from the first helical feeding member toward a downstream side of the first helical feeding member with respect to the first feeding direction to branch a flow path of the developer. With respect to the first feeding direction, the second region is provided between the first region and a position where the first and second helical feeding members cross each other.
