Abstract
Many holes are formed in a platen that supports a paper. A suction fan generates suction force through these holes to thereby bring the paper into close contact with a surface of the platen. Ink ejection regions to which printing heads eject ink are set on a paper supporting side of the platen. The holes are formed in other regions in the platen than regions corresponding to vicinities of longitudinal ends of the ink ejection regions.

An ink-jet printer comprising:
- a conveyance mechanism that conveys a printing medium;
- an ink ejecting member capable of ejecting ink to an ink ejection region elongated in a direction substantially perpendicular to a conveyance direction of the conveyance mechanism;

- and
- a suction member capable of sucking air through the hole from a printing medium supporting side of the supporting member to an opposite side thereof.
