ABSTRACT:
A developer cartridge includes an outer barrel member, an inner barrel member rotatably provided with respect to the outer barrel member, and a regulating member rotatably provided with respect to the inner barrel member. The regulating member includes a first engaging portion and a second engaging portion. The inner barrel member includes a first to-be-engaged portion that engages the first engaging portion and an operating member. The outer barrel member includes a second to-be-engaged portion that engages the second engaging portion. When the first engaging portion and the first to-be-engaged portion engage each other and engagement between the second engaging portion and the second to-be-engaged portion is released, the inner barrel member is rotatable together with the regulating member with respect to the outer barrel member. When engagement between the first engaging portion and the first to-be-engaged portion is released and engagement between the second engaging portion and the second to-be-engaged portion released, the regulating member is rotatable with respect to the inner barrel member.
