Abstract
An image forming device includes a plurality of cartridges each including a developing member, a supply member, a developing agent container, and a conveying member. The container is disposed below the developing member and the supply member and has an inner surface defining an internal space. The container has an opening having an upper edge and a lower edge. The conveying member is rotatably disposed in the internal space and is configured to convey the developing agent upward. The container includes a first wall portion extending from the lower edge in a downstream direction with respect to a rotational direction of the conveying member and includes a second wall portion extending from the upper edge in an upstream direction with respect to the rotational direction. The conveying member is in simultaneous sliding contact with both the upper and lower edges to convey the developing agent onto the first wall portion.
