Inkjet recording system and recording apparatus |
| abstract |
An inkjet recording system includes an inkjet recording head in which a part of wall face of a pressure chamber in which a nozzle is provided is formed of a piezoelectric element. Centerline average roughness Ra of the piezoelectric element is 0.05 to 2 μm, viscosity of the ink is 2.0 to 10.0 mPa·s, and the following expression (1) is satisfied; n r γ cos θ 2 η ≥ 0.07 ( 1 ) nwherein r represents centerline average roughness (μm) of surface of piezoelectric element forming wall face of the pressure chamber, γ represents surface tension (mN/m) of ink, η represents viscosity of ink (mPa·s), and θ represents contact angle (degree) of ink with respect to piezoelectric element. |
