Inkjet recording apparatus
Abstract:
An inkjet recording apparatus according to one aspect of the present disclosure includes nozzle, pressuring chambers, piezoelectric element, ambient condition obtaining portion, application portion, and control portion. Control portion causes application portion to output ejection driving-voltage by which piezoelectric element is deformed so as to eject droplets from nozzles in printing period in printing state, and causes application portion to output vibration driving-voltage by which piezoelectric element is vibrated so as to vibrate meniscus in each nozzle in non-printing period between printing periods in printing state. Control portion changes the number of times piezoelectric element is vibrated in non-printing period, based on ambient condition obtained by ambient condition obtaining portion, or zero shear viscosity of ink which is calculated or obtained according to obtained ambient condition, and causes application portion to output vibration driving-voltage by which piezoelectric element is vibrated the number of times having been changed.
