<p>PURPOSE:To obtain the ink for copy machine, being initially packed or repacked into a specific ink-jet cartridge, having specific surface tension, capable of preventing ink leakage, capable of improving smoothness of gas-liquid interface and minimizing variation. CONSTITUTION:This packing ink having >=20dye/cm surface tension and <=55dye/cm, preferably >=25dye/cm and <=50dye/cm is initially packed or repacked into a cartridge of the figure equipped with a first storage champing 1004 having a negative pressure generating member 1,003 and an atmospheric pressure communicating part 1,030 and a second storage chamber 1,006 which is connected only through a very small communicating part 1,008 to the first storage chamber 1,004 but is substantially in a closed state.</p> |
