PROBLEM TO BE SOLVED: To provide an image forming device made possible to obtain the excellent image being supreme in development property and the development stability by preventing the occurrence of absorption or void arising at the non- contact development, at the time of forming image on the image carrier, and to obtain the image of excellent hue, furnished with the second color enable inconspicuously changing. SOLUTION: This developing device at least, provided with a developing sleeve 41, carrying the developer, a magnet roll 42 placed inside the developing sleeve 41, arranging plural magnetic poles along the rotary direction of the developing sleeve 41, developing the electrostatic latent image formed on the photoreceptor 1 by developer held in a state of non-contact with respect to the photoreceptor 1, is allowed to set the section nearest to the photoreceptor 1 on the developing sleeve 41, between plural NS magnetic poles being respectively different, and to apply a voltage superimposing the intermittently suspended non-centrosymmetry AC component over the DC component, with respect to the developing sleeve 41. |
