PROBLEM TO BE SOLVED: To provide a method for securely heat transmitting the heat of an electromagnetic wave absorption layer to the surface of a recording layer in the emission of electromagnetic waves for a short time and also provide a device thereof. SOLUTION: A recording body 10 with a recording layer formed of a member of the nature of lowering the recessing contact angle when heating the same in the state of contact with a liquid is used, and the surface of the recording body 10 is heated selectively in compliance with image information by an electromagnetic generating source 11. Then, an image is visualized by developing the recording body on an ink roller 13 using a coloring material and transferred to a recording paper 20. The selective heating to the recording body 10 by the electromagnetic generating source 11 is the electromagnetic wave emission performing the pulse modulation, and the recording body 10 includes an electromagnetic wave absorption member absorbing the electromagnetic waves. The emission time of the electromagnetic waves to the recording body 10 is set at 10 nanoseconds to 10 microseconds, and the emission energy is set in the range from 50 mJ/mm2 to 500 mJ/mm2 to form a combination of the emission time with the emission energy not to heat decompose the electromagnetic absorption member. |
