Ink jet recording apparatus capable of performing liquid droplet diameter random variable recording and ink jet recording method using ink for liquid droplet random variable recording
 In a recording apparatus provided with a plurality of discharging ports for discharging ink, and discharging elements for discharging ink upon application of electrical pulses, the volume of ink droplets discharged from each of the discharging ports is caused to vary due to the properties of each discharging port. This variation results in a conspicuous unevenness in recording. The present invention provides a method for making such recording unevenness due to the properties of each discharging port inconspicuous by varying the volume of ink droplets discharged from each of the plural discharging ports at random. Also, the present invention provides a technique in which the volume of discharging ink droplets is varied at random by use of a specific ink in order to make the recording unevenness inconspicuous.
