Abstract:
1. An inkjet recording method comprising: discharging ink on a recording medium to form an image thereon, wherein the ink comprises: a hydrodispersible colorant having a functional group, a surfactant, water, a polyol having an equilibrium moisture of 30 percent by weight or greater at 23° C. and 80 percent RH, an amide compound represented by Formula I, and an oxetane compound represented by Formula II; wherein the recording medium has a transfer amount of highly deionized water of from 5 ml/m wherein the ink has a wettability γ′ cos θ of from 19.0 to 24.0 150 msec after ejecting 2.5 μl of the ink onto the recording medium and γ′ is 26 mN/m or less, where γ′ represents dynamic surface tension at a surface life of 150 msec at 25° C. and 50 percent RH as measured by maximum bubble pressure technique and θ represents a contact angle of 150 msec at 25° C. and 50 percent RH after 2.5 μl of the ink is ejected onto the recording medium, where R represents an alkyl group having 4 to 6 carbon atoms, where R
