PURPOSE:To prevent mixing of different color toners to obtain a color image without mixed color by reducing the quantity of electric charge of a toner of each developer in plural developing means toward succeeding-stage developing means. CONSTITUTION:A photosensitive drum 11 having a photosensitive layer 11a is rotated in the direction of an arrow and is charged electrostatically uniformly by a charger 12a, and an image is exposed in an exposure part 13a with respect to the first color, and a generated latent image is developed by a developing part 14. The photosensitive drum 11 is charged again uniformly by a charger 12b, and the image is exposed in an exposure part 13b with respect to the second color, and the image is developed by a developing part 14b and is transferred to a recording paper 19 by a transfer device 15. The quantity of electric charge of the toner in the first developing part 14a is made larger than that in the second developing part 14b, and thus, mixing of different color toners is prevented to obtain a color image without mixed color. |
