PROBLEM TO BE SOLVED: To provide an ink storage tank which can stir inside ink by only a channel structure and a channel shape and effectively prevent ink from settling while hardly complicating a head structure or hardly increasing costs. SOLUTION: An ink cartridge 1 for storing ink to be supplied to a recording head which discharges ink drops corresponding to printing signals is provided with a communication port 15A where ink flows. A stirring member 7 for stirring ink by changing the direction of the ink flowing the communication port 15A is set to the downstream side of the communication port 15A. The ink in the cartridge 1 is automatically stirred when flowing in the communication port 15A. The ink can be effectively prevented from settling by the simple structure without complicating the structure of the cartridge 1 or a recorder itself and without increasing costs as in the prior art. |
