摘要： A liquid ejection method includes a step of preparing a liquid ejection head including an electrothermal transducer element for generating thermal energy contributable to ejection of liquid, an ejection outlet for ejecting the liquid, the ejection outlet being provided at a position opposed to the electrothermal transducer element, and a liquid flow path in fluid communication with the ejection outlet to supply the liquid to the ejection outlet and having the electrothermal transducer element on its bottom side; and a step of applying the thermal energy to the liquid to cause the liquid to undergo a change of state and thus to create a bubble. The liquid is ejected through the ejection outlet by the pressure of the bubble. The bubble is first in communication with ambience during reduction of the volume of the bubble after the bubble reaches a maximum volume.

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.

摘要： A liquid jet recording head includes a liquid path communicating with a discharge opening through which a liquid is discharged; a plurality of heating elements disposed in the liquid path, each of the heating elements having a different minimum power requirement for enabling the liquid to be discharged; and electrodes for allowing electric power to be simultaneously supplied to the plurality of heating elements. This invention further provides a liquid jet recording apparatus having a liquid jet recording head constructed in the above-described manner. The power density of each heating element is varied by the application of a drive voltage, thereby enabling stable step control over the gradation of an image recorded without the need for complicated wiring.
