ABSTRACT:
A developer container has a cylindrical container body with a bottom end and an open end and a cap closing the open end of the container body. The developer container has a spiral rib, a outlet opening and a bank portion. The spiral rib is formed on the inner surface of the container body. The outlet opening is formed on the side surface in vicinity of one end of the container body, whereby the rotation of the container disposed horizontally causes a developer contained in the container to move to one end of the container along the spiral rib and to flow out through the outlet opening. The bank portion is formed on the inner surface at the upstream side of the outlet opening with respect to the rotational direction of the container, the bank portion being positioned in the vicinity of the outlet opening and being continuous with the terminate end of the spiral rib.
