Patent ID: 7441878

Claim:
An ink jet recording head comprising: a first nozzle array for discharging yellow ink; a plurality of second nozzle arrays for discharging cyan ink and magenta ink that have a higher visibility than that of the ink discharged by the first nozzle array; and an element substrate, including a first heat-generating resistor element array and a second heat-generating resistor element arrays, which correspond to the first nozzle array and the second nozzle arrays, and temperature adjustment heaters, wherein one of the temperature adjustment heaters is arranged adjacently to a cyan array of the plurality of second nozzle arrays in a direction perpendicular to the second nozzle arrays and is arranged only in an area between the cyan array of the second nozzle arrays and an end of the element substrate in the perpendicular direction, and another of the temperature adjustment heaters is arranged adjacently to a magenta array of the plurality of second nozzle arrays in the direction perpendicular to the second nozzle arrays and is arranged only in an area between the magenta array of the second nozzle arrays and an end of the element substrate in the perpendicular direction.
