A printing apparatus, comprising: a conveying unit including an upstream roller and a downstream roller located downstream of the upstream roller in a conveying direction and configured to convey a printing medium in contact with the upstream roller and the downstream roller in the conveying direction by rotating the upstream roller and the downstream roller; and an ink discharging unit configured to discharge ink to the printing medium being conveyed by the conveying unit; wherein: each of the upstream roller and the downstream roller is in contact with the printing medium on a peripheral surface having a concave shape which continuously increase a diameter from a center toward both ends in an axial direction; and the ink discharging unit discharges the ink to the printing medium located in a first range from an upstream end (Wuu) of an upstream contact part (Wu), where the upstream roller and the printing medium are in contact, to a downstream end (Wdd) of a downstream contact part (Wd), where the downstream roller and the printing medium are in contact, in the conveying direction, and wherein: the ink discharging unit includes a plurality of discharge heads (31a to 31d) which are arranged in the conveying direction and discharge the ink to a plurality of landing positions (La to Ld) arranged at intervals in the conveying direction in a second range from a downstream end (Wud) of the upstream contact part (Wu) to an upstream end (Wdu) of the downstream contact part (Wd) in the conveying direction; wherein the conveying unit further includes a plurality of intermediate rollers (26b to 26d) located between the upstream roller and the downstream roller in the conveying direction and configured to contact the printing medium between the landing positions (La to Ld) adjacent in the conveying direction; and the plurality of intermediate rollers (26b to 26d) are in contact with the printing medium on a peripheral surface shaped to increase a diameter from a center toward ends in an axial direction. a conveying unit including an upstream roller and a downstream roller located downstream of the upstream roller in a conveying direction and configured to convey a printing medium in contact with the upstream roller and the downstream roller in the conveying direction by rotating the upstream roller and the downstream roller; and an ink discharging unit configured to discharge ink to the printing medium being conveyed by the conveying unit; wherein: each of the upstream roller and the downstream roller is in contact with the printing medium on a peripheral surface having a concave shape which continuously increase a diameter from a center toward both ends in an axial direction; and the ink discharging unit discharges the ink to the printing medium located in a first range from an upstream end (Wuu) of an upstream contact part (Wu), where the upstream roller and the printing medium are in contact, to a downstream end (Wdd) of a downstream contact part (Wd), where the downstream roller and the printing medium are in contact, in the conveying direction, and each of the upstream roller and the downstream roller is in contact with the printing medium on a peripheral surface having a concave shape which continuously increase a diameter from a center toward both ends in an axial direction; and the ink discharging unit discharges the ink to the printing medium located in a first range from an upstream end (Wuu) of an upstream contact part (Wu), where the upstream roller and the printing medium are in contact, to a downstream end (Wdd) of a downstream contact part (Wd), where the downstream roller and the printing medium are in contact, in the conveying direction, and the ink discharging unit includes a plurality of discharge heads (31a to 31d) which are arranged in the conveying direction and discharge the ink to a plurality of landing positions (La to Ld) arranged at intervals in the conveying direction in a second range from a downstream end (Wud) of the upstream contact part (Wu) to an upstream end (Wdu) of the downstream contact part (Wd) in the conveying direction; wherein the conveying unit further includes a plurality of intermediate rollers (26b to 26d) located between the upstream roller and the downstream roller in the conveying direction and configured to contact the printing medium between the landing positions (La to Ld) adjacent in the conveying direction; and the plurality of intermediate rollers (26b to 26d) are in contact with the printing medium on a peripheral surface shaped to increase a diameter from a center toward ends in an axial direction.
