An ink jet printer includes a casing, a sub ink tank, an ink jet head, a main ink tank side connector, a sub ink tank side connector, a wall member and a breaking portion. The casing includes a space for housing a main ink tank. Ink within the main ink tank is to be supplied to the sub ink tank. Ink within the sub ink tank is to be supplied to the ink jet head. The main ink tank side connector is to be connected with the main ink tank. The sub ink tank side connector is to be connected with the sub ink tank. The main ink tank side connector is capable of moving with respect to the sub ink tank side connector between a first positional relationship and a second positional relationship. The main ink tank side connector is connected with the sub ink tank side connector in the first positional relationship. The main ink tank side connector is disconnected from the sub ink tank side connector in the second positional relationship. The wall member surrounds at least a connection portion of the main ink tank side connector and the sub ink tank side connector when the main ink tank side connector and the sub ink tank side connector are positioned in the first positional relationship. The breaking portion breaks an ink film formed within an inner space of the wall member. The ink film is formed when the main ink tank side connector moves with respect to the sub ink tank side connector from the first positional relationship to the second positional relationship. The breaking portion breaks the ink film in a state where at least a part of the ink film exists within the wall member.
