Abstract
A developer container includes a first housing, a rotator drawing a first rotation trajectory in the first housing, a second housing, a developer conveyor in the second housing, and multiple partitions between the first housing and the second housing. The second housing communicates with the first housing. The developer conveyor conveys developer from the second housing to the first housing and includes a rotation shaft and a flexible sheet extending from the rotation shaft. The developer conveyor is rotatable about the rotation shaft to draw an imaginary second rotation trajectory overlapping the first rotation trajectory under an imaginary condition in which the flexible sheet contacts no member and does not bend. The multiple partitions between the first housing and the second housing are arranged at intervals in a rotation shaft direction and are contactable by the flexible sheet rotating around the rotation shaft.
