An ink tank (10) is attachable to the attachment section by positioning first engagement sections (22) at first fitting sections (35) on the attachment section and then locking a second engagement section (23) to a second fitting section (5) of the attachment section by rotating the tank. The multiple supply ports (14) are arranged on a bottom face of the tank such that the supply ports (14) are on both sides of a center line (61) in a width direction of the tank, and that distances between each of abutting centers (26-29) configured to abut ink receiving parts of the attachment section, and the first engagement section side (22) in a direction along a center line are mutually different (a,b,c). It is possible to avoid reception of a reactive force to the ink receiving parts at one time when rotating and attaching the tank, and to achieve stable attachment while suppressing excessive inclination of the tank at the time of attachment. |
