Abstract:
1. A liquid jet head comprising: a nozzle plate formed of nozzles from which a liquid is ejected to a receiving medium, said nozzles being arranged to provide a density same as that of a flow path of the liquid jet head, wherein the liquid contains fine particles, wherein the fine particles contained in the liquid are no less than 1% by weight, wherein each of the nozzles has an area that is less than 500 μm wherein each of the fine particles has a diameter satisfying a relation of 0.0005≦Dp/Do≦0.02, wherein “Dp” represents the diameter of each of the fine particles and “Do” represents a size of each of the nozzles, wherein when the nozzle element ejects the liquid onto the receiving medium, a contact angle of the liquid stops changing when 100 ms or less elapses after the liquid contacts the receiving medium, wherein the receiving medium is a resin material and has a surface, and wherein the average diameter of the fine particles is smaller than smoothness of the surface of the receiving medium.
