A developer container includes a container housing for storing developer, a cylinder section projecting from the container housing and including a developer discharge port, and a rotary member for conveying the developer to the discharge port. The rotary member includes a rotary shaft rotatably supported and having a first part located in the container housing and a second part located in the cylinder section, and a resilient member projecting from the second part of the rotary shaft in a radial direction of rotation of the rotary member and facing the developer discharge port. The resilient member includes a tip end operable to protrude radially outward out of the developer discharge port after rubbing an inner surface of the cylinder section as the rotary shaft of the rotary member makes rotation.
