Zusammenfassung: | To provide a developer supply device that improves the degree of freedom in the distance and the direction from a discharge port to a toner supply destination.SOLUTION: A developer supply device has: a volume variable pump unit 21; a conveyance path unit 24 that has a connection port connected to the pump unit 21 at one end and has a discharge port 23 at the other end; and a toner storage unit 22 that is connected to a midpoint between the one end and the other end of the conveyance path unit 24 and stores toner. The amount of change in volume of the pump unit 21 is larger than the total volume from the connection port to the discharge port 23 of the conveyance path unit 24.SELECTED DRAWING: Figure 1
【課題】 本発明は、排出口からトナーの補給先までの距離や方向の自由度が向上する現像剤補給装置を提供する。【解決手段】 容積可変なポンプ部21と、一端にポンプ部21に接続する接続口を有し、他端に排出口23を有する、搬送経路部24と、搬送経路部24の前記一端と前記他端の途中に接続されると共に、トナーを収容するトナー収容部22と、を有し、搬送経路部24の前記接続口から排出口23までの総容積よりも、ポンプ部21の容積変化量が大きい、ことを特徴とする。【選択図】 図1 |
