A maintenance device for an ink-jet head having a head substrate on a surface of which orifices for ejecting ink droplets are formed in a row. A maintenance device includes a removal unit comprising a suction assembly which is disposed in a position that faces the surface of the head substrate having the orifices formed thereon and does not come into contact with the head substrate, and which has formed therein, on a surface opposite the head substrate surface on which the orifices are formed, a first and second suction ports, each being slit-like and elongated in a direction parallel to an orifice array direction; and a suction pump which draws air from inside the suction assembly.
