Abstract

A developer container includes a container body, a rotary shaft, a rotary stirrer, and a flexible blade. The container body contains developer and has a discharge port. The rotary stirrer includes a rotary support and rotates about the rotary shaft to stir and transport the developer. The rotary support includes a base end rotatable integrally with the rotary shaft, a free end spaced away from an inner wall of the container body, and a holding surface provided at the free end or at a position shifted toward the rotary shaft away from the free end. The holding surface is parallel to or inclined relative to a rotation direction of the rotary support. The flexible blade includes a base end portion held on the holding surface and a distal end to contact the inner wall and transport the developer to the discharge port.
