Document Type and Number:
Japanese Patent JP5239899
Kind Code:
B2
Abstract:
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.
