<P>PROBLEM TO BE SOLVED: To provide an image forming method capable of efficiently drawing images of high printing quality to be formed by using laser beam, and capable of improving durability of a heat reversible recording medium against repeated use. <P>SOLUTION: In this image forming method forming a two-dimensional code including drawing cells to be drawn by irradiating laser beam into the cells, in the case of continuously drawing the cells in an area wherein the drawing cells crowd, when energy density of the laser beam to be irradiated to at least one cell is E<SB>1</SB>and energy density of the laser beam to be irradiated to the cells in an area wherein the drawing cells do not crowd is E2, the energy density E<SB>1</SB>is set to be lower than the energy density E<SB>2</SB>. <P>COPYRIGHT: (C)2011,JPO&INPIT |
