PROBLEM TO BE SOLVED: To provide an ink jet head which is excellent in a meniscus stability while being able to hold the meniscus at a high position, to discharge an ink droplet stably and to improve the discharge responsiveness, and an image forming apparatus equipped with the same head. SOLUTION: The ink jet head includes a plurality of delivery perforations for discharging the ink droplet, a delivery electrode for making an electrostatic force affect the ink in corresponding to the perforations and an ink guide projecting from the perforations. The ink guide is equipped with a plate-like leg and a plate-like point extended from the end of the leg, and the point is arranged towards the droplet discharge side. The point is extended with a level difference so that it may have the same plane as the one of the end of the leg at the one surface side and may have the thickness thinner than the one of the leg at the other surface side. The point has a tip shape which becomes gradually thinner towards the droplet discharge side, and the electrostatic force affecting the ink has a component travelling towards the tip at least along with the tip.
