DEVELOPING AGENT CONTAINER, AND IMAGE FORMING DEVICE PROVIDED THEREWITH

摘要

This developing agent container (30) is provided with a container body (31), a movable wall (34), and a stirring member (32). The container body (31) is provided with an inner peripheral surface (31K) which defines an inner space (31H) which extends cylindrically along the longitudinal direction, and a developing agent discharge port (319). The developing agent discharge port (319) is an opening in the bottom of the inner peripheral surface (31K). The movable wall (34) is provided with a conveyance surface (340S), and an outer peripheral surface (34K) arranged slidably in close contact with the inner peripheral surface (31K) of the container body (31). The conveyance surface (340S) defines the housing space (31S) of the developing agent. The movable wall (34) moves while conveying the developing agent in the housing space (31S) towards the developing agent discharge port (319). The stirring member (32) stirs the developing agent that is inside of the housing space (31S).
