    • A developing apparatus includes a developer container to store a developer, a conveyance member to convey the developer, and a discharge port to discharge the developer. The discharge port is at a position that is on one end side from a central portion of the conveyance member with respect to an axial direction of the conveyance member. A first region of the conveyance member may include a portion facing the discharge port that has a conveyance capacity that is lower than a conveyance capacity of a second region or has a conveyance capacity that is zero. The conveyance member includes a positioning unit that is provided on the one end side thereof in the axial direction to position the conveyance member in the axial direction by abutting on the developer container, and an urging unit to urge the positioning unit with respect to the developer container.
    • 显影装置包括用于存储显影剂的显影剂容器,用于输送显影剂的输送构件和用于排出显影剂的排出口。 排出口处于与输送部件的中心部相对于输送部件的轴向的一端侧的位置。 输送构件的第一区域可以包括具有比第二区域的输送能力低的输送能力或具有为零的输送能力的面向排出口的部分。 传送构件包括定位单元,该定位单元在轴向的一端侧设置有用于通过抵靠显影剂容器而使输送构件沿轴向定位;以及推压单元,其相对于显影剂促使定位单元 容器。
