Abstract

In a liquid jet recording apparatus, a stable ink ejection/recording operation is realized, and a natural image with improved multi-gradation is recorded. In the liquid jet recording apparatus for mixing a dilution liquid with ink quantified by utilizing displacement of a piezoelectric device in response to print data, and for ejecting a mixture fluid made by mixing the ink with the dilution fluid so as to perform a recording operation, when the ink is quantified, a rising speed of a signal applied to the piezoelectric device is selected to be lower than, or equal to 1V/microsecond.
