A maintenance mechanism includes: a carriage 22 capable of performing reciprocating movement along a line parallel to an ink discharging surface 4 a; and a purge sheet 21 attached to the carriage 22 and capable of being located, depending on the carriage 22 position, in a purge position opposing the ink discharging surface 4 a and a printing position not opposing the ink discharging surface 4 a. When being in the purge position, the purge sheet 21 has such a shape that allows ink discharged from the ink discharging surface 4a and adhered to the purge sheet. 21 to move, owing to gravity, toward the center of the purge sheet 21 with respect to the width direction of the purge sheet 21 which is perpendicular to the traveling direction of the carriage 22.
