ABSTRACT:
An ink container has an atmosphere communicating section for placing the inside of the container in communication with the atmosphere. The atmosphere communicating section has a plurality of chambers, one of which communicates with the inside of the ink container, and another of which communicates with the atmosphere. Each chamber communicates with another chamber through a port smaller than the chamber. Preferably, the plurality of chambers are disposed in a direction intersecting a direction from the interior to the exterior of the ink container and the opening in the chambers are positioned such that they are shifted from each other. This arrangement prevents ink leakage through the atmosphere communicating section and eliminates a general feeling of anxiety on the part of users deriving from the possibility of having their hands and clothes soiled with spilt ink. It also inhibits ink evaporation.
