Abstract:
The inkjet ink includes at least a carbon black, a surfactant, a polyether-modified silicone oil having a polyoxyalkylene group in a side chain thereof, an anionic self-emulsifying polyether-modified polyurethane resin having a polyoxyalkylene group in a main chain thereof, and water. The inkjet ink contains particles having a particle diameter of not less than 0.5 μm in an amount of from 500,000 to 2,000,000 pieces per 5.0 μl, and has a volume average particle diameter (D50) of from 80 nm to 120 nm and a 90% cumulative particle diameter (D90) of from 160 nm to 200 nm.
