An image recording apparatus is provided containing:

Inkjet image forming apparatus and inkjet image forming method

An ink jet recording method including: applying at least two energy beam curable liquids different from each other in surface tension on a recording medium to form an energy beam curable liquid layer having a distribution pattern of different surface tensions; ejecting an energy beam curable ink on the energy beam curable liquid layer formed on the recording medium; and irradiating the energy beam curable liquid layer and the energy beam curable ink with energy beams to cure the energy beam curable liquid layer and the energy beam curable ink to form an image.

There is provided a method of manufacturing a hollow structural member suitable for precisely manufacturing a hollow structural member whose pitch space of the hollows is below 30 &#x3bc;m. The method of manufacturing a hollow structural member of this invention is to encapsulate, by using a gas-permeable material in part of a material that constitutes the substrate () for manufacturing the hollow structural member, a high-pressure gas by injection in advance, under high-pressure conditions, into the gas-permeable material; to form a plastic deformation film () on a surface under reduced-pressure conditions; and to expand and draw the plastic deformation film (), while preventing the plastic deformation material from entering the recesses (), by discharging the high-pressure gas that is encapsulated in the gas-permeable material into each of the recesses (), whereby the hollow structural member is manufactured.
