摘要:
When ejectors (nozzles) are viewed in order in a sub-scanning direction, the ejectors are arranged so that positions of the ejectors in a main scanning direction alternate in an offsetting manner. When formed dots are viewed along the sub-scanning direction, sizes of the dots are changed at random. Accordingly, density unevenness is decreased, the ejectors can be arranged in high density, and an image can be recorded at high speed. That is, the invention provides a droplet ejecting head in which density unevenness which tends to be generated in a head having a matrix-like nozzle arrangement can be decreased without decreasing recording speed and thus high-speed recording is made compatible with high-quality recording. The invention also provides a droplet ejecting apparatus which is provided with the droplet ejecting head.
