DEVELOPER CONTAINER AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

A developer container includes a container body, a movable wall, and a detection sensor. The container body includes an inner surface defining a cylindrical internal space. The internal space is in the form of a cylinder extending in a first direction. The container body is formed with a developer discharge port communicating with the internal space. The movable wall includes an outer surface and a conveying surface. The outer surface is disposed in close contact with the inner surface of the container body. The conveying surface defines a storage space configured to contain the developer in cooperation with the inner surface of the container body. The movable wall moves in the first direction from one end side to the other end side of the internal space. The detection sensor is provided on the container body near the developer discharge port and detects the developer in the storage space.
