ABSTRACT:
An ink tank includes a first channel extending in the form of a groove on an external part of the tank in connection with an atmospheric communicating port. The tank also includes a second channel which branches off from the first channel and joins this again and which has a capillary force greater than that of the first channel. Even when some amount of ink has flowed out of the atmospheric communicating port, the capillary force generated in the second channel acts to hold the ink in the channel. Additionally, even when ink is stored in the second channel, the first channel is not closed, and the pressure in the tank is therefore kept in equilibrium with the atmospheric pressure. Therefore, there is little possibility that the ink in the second channel will be pushed out even when the ambient temperature changes.
