Claim:
1. An inkjet ink comprising a functional particle having a BET-equivalent average particle diameter of 50 nm to 1000 nm; a rheology-controlling particle having a BET-equivalent average particle diameter of 4 nm to 40 nm; and an organic vehicle, wherein an amount of the functional particle is in a range of 3.5% by volume to 6.9% by volume of the inkjet ink, the inkjet ink has a viscosity of 1 mPa·s to 50 mPa·s at a shear rate of 1000 s the inkjet ink has, at a shear rate of 0.1 s where D is the BET-equivalent average particle diameter of the functional particle, and ρ is a specific gravity of the functional particle.
