Problems solved by technology
However, if the ink in the ink bag cannot be used up, the frequency of replacement will increase and the workload of the user will increase, and the replacement of the ink bag with ink remaining will cause user dissatisfaction.
[0007] In addition, since the expanded part of the ink bag is stretched when the ink is filled with ink, the wall part of the ink bag cannot be bent when the ink is reduced, and the ink cannot be discharged and remains in the ink bag 102.
In particular, when the ink bag is placed in a state of being transported or stored, the ink bag is easily affected by spreading, and ink tends to remain on the side away from the fixed part of the ink bag on the ink tank.
In addition, even if a space where the ink bag can be stretched and deformed is provided inside the ink tank, it cannot be avoided that such bending difficulties occur in the wall-mounted part.

An ink container includes a liquid storing container and a container case. The liquid storing container is filled with an ink and provided with a spout discharging the ink at one end side. The container case contains the liquid storing container and fixes one end of the liquid storing container. The ink storing container contracts and lengthens in forward and backward directions in accordance with reduction in the ink from a state where the ink is filled inside. The container case includes a first housing part and a second housing part. The first housing part houses the liquid storing container in an ink filled state. The second housing part has the height dimension smaller than the height dimension of the first housing part and houses a lengthened amount of the liquid storing container at another end side of the first housing part depending on the reduction in the ink.
Description
technical field [0001] The present invention relates to an ink cartridge and an inkjet image forming apparatus having the ink cartridge. Background technique [0002] An inkjet image forming apparatus forms an image on a paper surface by ejecting ink from a recording head onto the paper. In addition, the ink ejected from the recording head to the paper is supplied to the recording head from the ink tank. [0003] The ink tank is configured corresponding to each image forming apparatus, for example, there is a type of ink tank that holds large-capacity ink. In addition, an ink bag is housed in an ink tank holding a large-capacity ink, and the ink bag contains ink, and the ink is discharged from the ink bag. As an example, such as Figure 16 and Figure 17 As shown, the ink cartridge 101 is composed of an ink bag 102 filled with ink and an ink cartridge case 103 in which the ink bag 102 is housed. The above-mentioned ink bag 102 is formed by forming a flexible film materia...
