ABSTRACT:
The ink jet recorder serves to record an image corresponding to image data on a recording medium using the ink jet head which discharges ink containing colored fine particles. The ink jet head includes a discharge opening substrate through which discharge openings through which the ink is discharged are bored, a head substrate which is disposed at a predetermined distance from the discharge opening substrate so as to define an ink passage between the discharge opening substrate and the head substrate, and a discharge control portion which controls the discharge of the ink through the discharge openings. An ink guide groove is formed in a surface of the discharge opening substrate on a side of the ink passage so as to lead from an upstream side of an ink flow to the discharge opening.
