PROBLEM TO BE SOLVED: To provide an image forming device having an electrifier that prevents scratch on a surface of the photoreceptor, performs efficient electrification at a low voltage, and generates little ozone. SOLUTION: The photoreceptor is electrified heretofore by bringing an electrifying roller into direct contact with the photoreceptor. According to the present invention, the surface of the electrifying roller 10 is provided, via gap fixing members 12, with an extremely minute space 11 that is uniform in the longitudinal direction of the photoreceptor. The electrifying roller 10 has a conductor 15 around a metal core 14 having a shaft part 13, and is urged close to the photoreceptor 20 by a spring (not shown) in figure which abuts on a side face of the shaft part. The electrifying roller 10 also applies a voltage from a high voltage power source 16 via the spring. The voltage applied to the core 14 is carried to a surface of the conductor 15, thereby electrifying the surface of the photoreceptor 20 in the area where both the surfaces are close to each other. The space fixing members 12 are disposed out of an image formation area of the conductive member 15. |
