| description | To suppress reduction of the charge provision capability of a developer due to attachment of an external additive on a surface of a carrier.SOLUTION: An image formation device according to an embodiment includes: a photosensitive body having a surface on which a toner image is to be formed; a developer having an auger for supplying a developer including a toner and a carrier; and a control unit for controlling execution of a carrier refresh mode by driving an auger on the basis of the toner in the developer becoming smaller than a threshold value.SELECTED DRAWING: Figure 1
【課題】現像剤のキャリアにトナーの外添剤が付着することがあり、外添剤がキャリアの表面に付着することによる現像剤の帯電付与能力の低下を抑制する。【解決手段】一態様の画像形成装置は、トナー像を形成する表面を有する感光体と、トナー及びキャリアを含む現像剤を供給するオーガーを有する現像装置と、現像装置におけるトナーの残量が閾値より小さくなったことに基づいてオーガーを駆動させることにより、キャリアリフレッシュモードの実行を制御する制御部と、を備える。【選択図】図１ |
