PROBLEM TO BE SOLVED: To provide an image forming device that provides an image whose half tone is highly uniform even in a system where an image carrier or an image forming device in the vicinity of the image carrier is coated with a lubricant for low friction and that prevents void in the rear end of an image. SOLUTION: A developing sleeve 43 has a magnet roll 44 fixed to the inside of the sleeve. The magnet roll 44 has auxiliary magnets P1a and P1c, adjacent to a developing main magnet P1b, which adjust half width of the main magnet P1b. The friction factor of the photoreceptor drum 1 is higher than or equal to 0.02. |
