Abstract
According to a first invention, since a flow of a spacer dispersed liquid is formed in a transporting chamber separated from a discharging chamber by an internal filter, the spacer dispersed liquid is stably discharged through an ejection hole, while the discharging chamber on a side of a nozzle plate is not affected by the flow of the spacer dispersed liquid. According to a second invention, since a spacer dispersed liquid does not flow inside a discharging chamber in a printing state in which the spacer dispersed liquid is discharged, the spacer dispersed liquid is stably discharged through an ejection hole. To the contrary, since the spacer dispersed liquid is directed inside both the discharging chamber and the transporting chamber in a waiting state in which the spacer dispersed liquid is not discharged, spacer particles in the spacer dispersed liquid do not settle.
