Abstract: A method for recovery of a recording head includes cleaning liquid supplying operation, wiping operation, and backflow operation. The recording head is connected to a cleaning liquid tank for storing cleaning liquid via a cleaning liquid supplying path. In the backflow operation, a liquid supply mechanism makes the cleaning liquid in the cleaning liquid supplying path to flow backward in a direction pointing from the cleaning liquid supplying openings to the cleaning liquid tank. The recording head includes an ink ejection region in which ink ejection openings are open, and a cleaning liquid supplying region which is arranged upstream of the ink ejection region in a wiping direction and in which cleaning liquid supplying openings are open. The backflow operation is performed after a wiper passes the cleaning liquid supplying region and before the wiper reaches the ink ejection region.

Abstract: An ink for ink-jet recording apparatuses includes water, a pigment dispersion, an organic solvent, and a humectant. The pigment dispersion includes a pigment and a resin having a weight average molecular weight of from 35,000 to 140,000. An adsorbed resin proportion determined from the mass of a total amount of resin in the ink and the amount of resin separated from pigment among the resin is at least 0.97. And, the ink contains from 3% to 15% by mass of C1-C4 monoalkyl ether of polyhydric alcohol based on the mass of the ink as the organic solvent.

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.
