PROBLEM TO BE SOLVED: To efficiently form a good quality image by a color image forming device by which an image having a high image quality can be obtained and time necessary to form an image can be shortened and which is excellent in environment preserving performance and energy-saving performance. SOLUTION: Toner having the same color is used in a first developing means 37 and a second developing means 39, and when toner having luster higher than the second developing means 39 side is used for the first developing means 37 side to form a color image, a lustrous, convergence error uncausal and high image quality color image can be obtained, and when toner having luster lower than the first developing means 37 side is used for the second developing means 39 side to form a monochromatic image, a nonlustrous and easy-to-see color image can be obtained in a short time. |
