PURPOSE:To provide an ink tank which can charge ink with a low-priced device, maintain charged ink uniformly and use the ink up to the bottom, and a method for ink charging into the ink tank. CONSTITUTION:An ink introducing pipe 2 is opened, and an ink holding member 3 is compressed with a compression pad 5. After the completion of compression, the ink introducing pipe 2 is closed. Ink is charged at a fixed pressure through an ink charging pipe 6. The charged ink is penetrated into the ink holding member 3. The pressure in an ink tank rises with the charged ink to push up the compression pad 5 from the inside of the ink tank. As a result, the pressure in the ink tank returns to a normal condition, and at the same time, penetration of ink into the ink holding member 3 and release of the compression condition are carried out, thus charging ink into the ink holding member 3 uniformly. At the time of compression release, the ink holding member 3 is prevented from floating with a fixed rib 4. |
