Abstract: An image corresponding to a single sheet of recording paper is divided into three decomposed images(1,2,3) each having the substantially same expansion as that of the image, and one of the decomposed images is recorded on the recording paper while a drum is rotated and the recording head is continuously moved at a distance corresponding to a width of the recording head. Subsequently, other decomposed images are successively recorded on the recording paper. Thus, recording of the respective decomposed image is performed at a predetermined time interval kept between two continuous recordings. The foregoing time interval can be used as a time required for ink permeation into the recording medium.

Abstract: A fluid ejection head comprises a heater (5) in a face within a fluid path (1). A bubble is generated by suppling electric power to the heater (5), and ink is ejected almost in a direction parallel to a face of the heater (5). The fluid path (1) further comprises a first part having a constant-section area being adjacent to an ejection orifice (2) a second part which exists behind the first part containing the heater, the cross-section area of the second part increasing by twice as large as the cross-section area of the ejection orifice (2), a length (A) between an end of the first part and a top end of the heater (5) is greater than or equal to a half of a height Ph of the ejection orifice.

Abstract: A liquid jet recording method of recording on a recording material with liquid droplets discharged through plural scanning nozzles, in which: n/(s/p)>/=2 n/(s/p)xk=g-1 are satisfied, where n (n>/=2) is a number of the nozzles arranged at pitch P ( mu m); s ( mu m) is a distance of relative movement between the nozzles and the recording material between adjacent scans; k (k>/=1) is a maximum number of ink droplets per pixel and per scan; g (g>/=3) is a number of tone levels.

Abstract: Each of pixels (No. 1 to N) of recorded image is formed by a plurality of dots composed with ink droplets ejected from a plurality of different orifices (No. 1 to M) at individual different main-scannings (No. 1, 2, 3 and so on). With this recording process, the variation of ink ejection characteristics between a plurality of orifices in a recording head can be reduced in forming pixels.

Abstract: Disclosed is a recording apparatus for performing recording using an ink-jet recording head (1) for discharging an ink from an array of a plurality of orifices, including a drive unit for driving the recording head (1) on the basis of a recording signal to cause a first orifice of the plurality of orifices to discharge an ink at a first timing, and to cause a second orifice to discharge an ink at a second timing, and a moving unit for moving the recording head (1) and a recording medium (2) relative to each other by an amount corresponding to a distance between the first and second orifices during a time interval between the first and second timings by the drive unit. There is also disclosed a recording method.
