PROBLEM TO BE SOLVED: To prevent color mixture caused by an ink leakage from ink supply ports at a setting/detachment operation in an ink tank device which stores many kinds of ink separately in each of storage chambers. SOLUTION: Grooves 410 of a predetermined depth are set between ink supply ports 401 for each of yellow (Y), magenta (M) and cyan (C) colors in an ink tank 400. The ink supply ports 401 for each color ink are separated by the grooves 410. Even if the ink leaks from any of the ink supply ports 401, mixing of inks between at least different colors are prevented accordingly. |
