Abstract
An ink jet recording apparatus, which records with deposition of ink droplets onto a recording medium by use of an ink jet recording head, includes a platen for supporting a recording medium in a position facing the ink jet recording head, a plurality of carrier roller pairs for nipping and carrying the recording medium to the position of ink deposition by the ink jet recording head and extrusions extended in the carrying direction of the recording medium with respect to the platen and arranged in the direction intersecting the carrying direction of the recording medium to support the reverse side of recording medium. The carrier roller pairs are positioned on each of the extended lines of the extrusions on the upstream side relative to carrying direction of the recording medium. With the structure thus arranged, the floating of a recording medium from the platen can be suppressed so as to allow the gap to be formed narrower between the recording medium and recording head, hence making it possible to perform recording in higher quality.
