Abstract:
An ink jet recording head, includes a nozzle array of nozzle flow paths; ink ejection orifices communicating with the nozzle flow paths; heaters in the nozzle flow paths; and ink with which the head is filled. The ink contains a coloring material, an acetylene glycol-based surfactant, and water, the surfactant containing one or more kinds of an acetylene glycol or an ethylene oxide adduct thereof, an average addition number of moles of ethylene oxide of the whole surfactant being 3 to 7. The ink has a viscosity of 1.5 mPa·s to 3.0 mPa·s. The head is a line type head having an opening area of each ink ejection orifice of 100 μm2 to 350 μm2, a total number of nozzles of 1,200 or more, and a length of the nozzle array of 2 inches or more, and the head is driven at a frequency of 1 kHz to 10 kHz.
