ABSTRACT:
An air passage is defined by and between an air nozzle plate having at least one air discharge port and an ink nozzle plate having a plurality of ink discharge ports, and projections are disposed in the air passage between the ink discharge ports and extend in a direction normal to the direction in which the ink discharge ports are arrayed, each of the projections having a length smaller than the width of the air passage. The projections substantially divide the air passage in the direction of the array of the ink discharge ports into different sections associated with the ink and air discharge ports. The projections may be structurally integral with the ink nozzle plate or the air nozzle plate so that an ink jet recording head can simply be assembled.
