ABSTRACT:
The inkjet recording apparatus having ink, where the inertia of ink in a flow passage is M, a viscosity resistance of the ink in the flow passage is R, and a return force of a meniscus is K in a nozzle, when the ink is charged in the flow passage composed of a nozzle and a pressure generating chamber, the physical properties of the ink and the share of the flow passage are set such that, a relationship of 0.2≦γ2/ω2≦1.0 is satisfied, where ω=√{square root over (K/M)} and γ=R/2M.
