PROBLEM TO BE SOLVED: To prevent the inadvertent rising of recording paper surely and to discharge the recording paper stably by sucking the recording paper by sucking air in a printing area by an ink bead. SOLUTION: Conveying rollers 12 the diameter of which is smaller than those of a resist roller 6 and a delivery roller 9 are held at a constant distance from the ink head 8 of recording paper P and installed in parallel in the printing direction, and a triangular support member 13 is arranged between the rollers 12 so that its plane part can contact the recording paper P. Air suction passages 14 for sucking air from the space between the roller 12 and the support member 13 are formed in the lower parts of the rollers 12 and the support member 13 to constitute a suction apparatus 11. Each roller 12 is rotated by a driving motor, which is a driving means for rotating the delivery roller 9, and conveys the recording paper P to be supplied by way of the resist roller 6 while the paper P is sucked by suction force acting between the roller 13 and the support member 13.
