To provide a pigment fine dispersing method, which can optimize printing quality, and an inkjet recording body, which has an ink accepting layer formed by coating a fine dispersion obtained through the method and which can output an image having a high printing density and being excellent in surface smoothness, lustrous properties, printing grade and water resisting properties of ink and has a high resolution equal to that of a silver salt photography.

This inorganic fine particle dispersion is set to be prepared in the preparing method of inorganic fine particle fine dispersion, in which the inorganic fine particle fine dispersions are opposedly collided against each other in flow passages of dispersions through orifices having the minimum flow passage area of at least 0.1 mm2 under the pressure range of 20-300 MPa, by passing the dispersions under the existence of at least each one site having a flow passage area same as or smaller than the flow passage area of the orifice in the passages of dispersions before and after the orifice.
