ABSTRACT:
A developing apparatus includes a developer container that contains a developer and a supply device that supplies a supply developer to the developer container. A feeding member that feeds the developer is disposed close to a discharge opening in the developer container, which allows the discharge of the developer contained in the developer container. The feeding member has a developer feeding power in an opposing area, in which the developer feeding member is opposed to the discharge opening, larger than a developer feeding power in an upstream-side area, which is upstream of the opposing area with respect to a developer feeding direction. Further, the feeding member has a developer feeding power in a downstream-side area, which is downstream of the opposing area with respect to the developer feeding direction, equal to or larger than the developer feeding power in the opposing area.
