Abstract:
A recording apparatus comprising:an ink transfer block for retaining an ink;a heating means for heating the ink retaining in the ink transfer block correspondingly to information to be printed, thereby developing a surface tension gradient and interfacial tension gradient on the ink surface, and a fluidity caused by the surface tension gradient and/or interfacial tension gradient of the ink surface is utilized to have the ink fly from the ink transfer block, thereby printing the information on a print receptor,whereby the heating means having a heating velocity v (in K/s) which meets the following:(T.sub.b -T.sub.i)/v>h.sup.2 /Dwhere T.sub.b : Boiling point of the ink in KT.sub.i : Initial temperature of the ink in Kh: Shortest distance between the surface of the heating means and ink surface in mD: Coefficient of thermal diffusion in m.sup.2 /s.
