摘要： The present invention provides an ink jet printer which performs recording by causing a nozzle to discharge an ink drop onto a recording medium. The nozzle is connected to an ink channel in which aqueous ink is housed. The printer head can vary the dot size on the recording medium by changing the size of the drop that is discharged from the nozzle. The aqueous ink has a degree of surface tension change .DELTA.S that is expressed by the relation .DELTA.S=(S.sub.1 -S.sub.3)/ S.sub.2 of 0.3 or less, wherein S.sub.2 is the surface tension at 25.degree. C., and has a value of 20 to 50 dynes/cm, S.sub.1 is the surface tension at 5.degree. C., and S.sub.3 is the surface tension at 40.degree. C.

摘要： An ink jet printer includes a piezoelectric element, and a voltage generation device for applying a voltage to the piezoelectric element. The voltage generation device applies a pulse voltage having a rising edge, a constant amplitude holding portion, and a falling edge for driving a piezoelectric element, whereby ink dots of a plurality of diameters are printed out to reproduce a half tone image. The waveform of the pulse voltage has the voltage boosted more gentle as the pulse amplitude becomes greater. The sudden strain of a piezoelectric element is prevented. An ink droplet of a particularly great diameter can be sprayed out stably. The conventionally encountered satellite dot, dot split noise, and ink hit position offset are prevented.
