In a developer detection device configured to detect that a developer container is filled with recovered developer by blocking detection light directed from a light-emitting element to a light-receiving element, the developer container is mounted at a predetermined mounting position. A developer detection device characterized in that a detection member is provided which moves by being pushed by a developer container, the light emitting element is attached to the detection member, and the light receiving element is attached to a fixed machine stand side.
