1. A device comprising:
a flow path member including a flow path configured to direct flow of a pseudoplastic liquid through the flow path member, wherein the flow path includes
a supply reservoir,
a plurality of supply manifolds connected to the supply reservoir, and
a plurality of pressure chambers connected in a one-to-one manner to a plurality of supply flow paths,
an actuator configured to apply pressure to the liquid in the plurality of pressure chambers to cause droplets to be ejected from a plurality of nozzles connected in a one-to-one manner to the plurality of pressure chambers;
a pump configured to cause the liquid to flow sequentially through the supply reservoir, the plurality of supply manifolds, the plurality of supply flow paths, and the plurality of pressure chambers; and
a controller configured to adjust a flow rate of the liquid to a prescribed target flow rate;
wherein the flow path has a flow path shape in which an average viscosity of the liquid in the plurality of supply flow paths is less than or equal to half an average viscosity of the liquid in the plurality of supply manifolds when the flow rate is equal to the target flow rate.
