Abstract
This invention provides an ink jet recording head for discharging an ink droplet using the thermal energy of heating means. According to the present invention, the heating means is a heating device having the Metal-Insulator-Metal type current-voltage properties in which the resistance value on the application of a low voltage exhibits a value higher than the resistance value on the application of a high voltage, regardless of the polarity.
Claims18
An ink jet recording head for discharging an ink droplet using the thermal energy of heating means, wherein said heating means is a heating device having Metal-Insulator-Metal type current-voltage properties in which the resistance value on the application of a low voltage exhibits a value higher than the resistance value on the application of a high voltage, regardless of the polarity.
An ink jet recording method comprising the steps of applying voltage to heating device having Metal-Insulator-Metal type current-voltage properties in which the resistance value on the application of a low voltage exhibits a value higher than the resistance value on the application of a high voltage, regardless of the polarity, to heat the heating device, and heating ink by the heat of said heating device, to bubble the ink and increase the pressure, thereby to discharge an ink droplet.
