摘要： A fluid ejection head comprises a heater disposed in a fluid path. A bubble is generated by supplying electric power to the heater, and ink is ejected in a direction substantially parallel to a face of the heater. The fluid path is shaped to have a first part with a constant-sectional area adjacent to an ejection orifice a second part located behind the first part and containing the heater. The cross-sectional area of the second part increases by twice as large as the cross-sectional area of the ejection orifice, a length (A) between an end of the first part of the fluid path and a top end of the heater is greater than or equal to half of the height Ph of the ejection orifice, and a shortest gap between the ejection orifice and the heater is less than or equal to a sum of a half of the height Ph of the ejection orifice and a length (L) of the first part of the fluid path.

摘要： A liquid jet recording method for recording on a recording material with liquid droplets discharged through plural scanning nozzles arranged in a width measured in a direction of main scan. The recording method includes a first main scan by relative movement between the nozzles and the recording material, in which pixels are recorded with numbers of droplets through a nozzle, the numbers of droplets corresponding to respective tone signals. The method also includes a sub-scan by relative movement between the nozzles and the recording material in a direction crossing with a movement direction of the first main scan. The method further includes a second main scan in which the pixels are recorded with numbers of droplets through a different nozzle, the latter numbers of droplets corresponding to tone level signals. The sub-scan and second main scan steps are repeated to record a tone image by discharging plural droplets for a pixel.
