Abstract (en)
An ink storage container having a simply configured ink exchange function is provided, whereby the amount of stored ink is increased. An air flow control unit for controlling the flow of air between the inside and outside is disposed in an ink storage unit for storing ink. The air flow control unit includes: a valve element that is formed of an interconnected porous material and allows air to be exchanged between the inside and outside of the ink storage unit according to positive and negative changes in the internal pressure of the ink storage unit; and a liquid repellent membrane that has air permeability and liquid repellency and is disposed on an ink side of the valve element.
