ABSTRACT:
In electrostatic inkjet recording in which an ink droplet is ejected by acting electrostatic force on ink that contains colorant particles, the electric conductivity of the colorant particles in the ink is saturated. Thus, variations in ink dot diameter caused by the ejection delay and a decrease in frequency responsivity are avoided, so that high-quality image recording with good frequency responsivity can be realized.
