    • An image forming apparatus includes a recording head, a sub-tank, a main tank, a supply unit, a memory, and a controller. The sub-tank includes an ink storage container, a flexible member, an elastic member, and an atmosphere-communicable unit. The ink storage container has an opening sealed by the flexible member biased by the elastic member. The main tank stores ink to be supplied to the sub-tank. The controller controls an ink dispensing operation depending on image forming conditions. The controller determines whether a gas bubble intrudes in the sub-tank. The controller executes the ink dispensing operation from the recording head using a dispensable ink volume when an ink supply from the main tank to the sub-tank is unable to be continued. The controller variably sets the dispensable ink volume. The controller determines that an ink end condition occurs when the recording head dispenses the dispensable ink volume from the sub-tank.
    • 图像形成装置包括记录头,副容器,主容器,供给单元,存储器和控制器。 副容器包括墨水储存容器,柔性构件,弹性构件和大气连通单元。 储墨容器具有由被弹性构件偏压的柔性构件密封的开口。 主罐储存供应给副罐的油墨。 控制器根据图像形成条件控制墨水分配操作。 控制器确定气泡是否侵入副油箱。 当从主容器向副容器的供墨不能继续时,控制器使用可分配的墨水量从记录头执行墨水分配操作。 控制器可变地设置可分配的墨水量。 当记录头从副罐分配可分配的墨水量时,控制器确定发生墨水结束状况。
