PROBLEM TO BE SOLVED: To provide an electric contact material manufacturing method and an electric contact material capable of appropriately setting amount of graphite on the surface of a metal body. SOLUTION: A photosensitive drum 13 is charged with electricity by a static charging mechanism 14, the photosensitive drum 13 after the static charging is rotated for a given number of times, and then, an exposure mechanism 15 irradiates light on the photosensitive drum 13 to form a latent electrostatic image on the surface of the drum 13. The photosensitive drum 13 is further rotated with a prescribed angle, a development mechanism 16 develops charged graphite particles on the photosensitive drum, and the graphite particles are adhered to the latent electrostatic image of the photosensitive drum. Next, a part with the graphite particles adhered of the photosensitive drum 13 is made rotated up to a position where it faces a sample 11, and a transfer mechanism 17 transfers the graphite particles to the sample 11 by giving reverse charge on the rear surface of the sample 11. Then, the graphite particles transferred to the sample 11 are fixed to the sample surface by a fixing mechanism 18. COPYRIGHT: (C)2007,JPO&INPIT
