摘要： Fluttering of paper traveling opposite to and parallel to a nozzle width region of an ink jet head is held down, thereby improving the printing quality.An ink jet recording apparatus comprises an ink jet printer including printing units (7, 7′) whereby a sheet of paper (2) traveling in a paper passage in the form of an arch shaped by a plurality of guide rollers (12a-12h) is printed by a plurality of ink jet heads (6a-6d, 6a′-6d′). The ink jet heads of the printing units comprise ink jet heads of on-demand type having a plurality of nozzle rows of a nozzle width region in a direction of travel of paper. The paper passage opposite to nozzle faces of each ink jet head nozzle defined by two guide rollers (12a, 12b) positioned at an upstream and at a down-stream side in the direction of travel of paper, respectively. Respective end portions of the upstream and downstream sides of the nozzle width region of each ink jet head in the direction of travel of paper are positioned at a first and a second area, respectively, which are between the upstream and downstream guide rollers and inside a first and a second point of paper winding contact with the guide rollers but which are approaching to the first and second points of paper winding contact, respectively, as much as possible.
