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.

Abstract: A negative-type image recording material comprising a support having a rear surface and an image recording layer disposed on the support, the image recording layer having a front surface and including (A) a radical-generating agent and (B) a radically polymerizable compound, wherein a static friction coefficient between the front surface and the rear surface is less than 0.50. In order to achieve such a specified static friction coefficient, it is preferable that the image recording layer contains (D) a compound represented by the following formula (1): R -X wherein R represents an optionally substituted hydrocarbon group having a total of 8 to 32 carbon atoms, and X represents CO-Y-R , NH-CO-NH-R , SO2-Y-R , or Y-R in which Y represents O, S, NR or a single bond.
