INK SUPPLIER

An ink supplier includes: a supply reservoir storing ink to be supplied to a plurality of heads; and a discharge pipe 71 used for discharging the ink from the supply reservoir. The supply reservoir includes: a cylindrical first horizontal reservoir 51 having a plurality of supply ports each communicating with one of the plurality of heads; and a first vertical reservoir 52 having a side surface provided with a first opening communicating with one end of the first horizontal reservoir 51. The first horizontal reservoir 51 has a bottom surface that is tilted from a horizontal direction at an angle of tilt equal to or greater than 0.3° in such a manner as to extend downward from the one end toward the other end. The first horizontal reservoir includes a first discharge port 81 provided at a bottom portion of the first horizontal reservoir at the other end and communicably connected to the discharge pipe 71. Thus, a precipitate in the first horizontal reservoir 51 moves along the tilted bottom surface and gathers at a lowermost point at the other end where the first discharge port 81 is provided. This allows the precipitate in the first horizontal reservoir 51 to be discharged efficiently. Specifically, a technique allowing a precipitate in a tank to be efficiently prevented from entering a head is provided.
