An ink tank is to be held detachably on a tank holder provided with a movable lever having a first engaging pawl to engage with a first engagement hole provided for one side wall of the tank holder, and a second engaging pawl to engage with a second engagement hole provided for side wall opposite to the one side wall having the first engagement hole of the tank holder. For this ink tank, the distance S between the outer side face of the base portion of the movable lever of the ink tank and the leading end of the second engaging pawl is set to be larger than the distance between the inner wall faces of the side wall having the first engagement hole of the tank holder and the side wall having the second engagement hole. With the structure thus arranged, unless the ink tank is kept in the normal posture, the ink tank is not allowed to enter the tank holder, hence enabling the user to recognize it easily and prompt him to operate the installation of the ink tank correctly.
