<p>PROBLEM TO BE SOLVED: To decrease toner consumption while assuring a color toner image of high image quality, which is formed by superimposing toners in a plurality of colors. SOLUTION: Each of the toners in a plurality of colors is flat toner whose equivalent circle diameter (d) as viewed from the direction in which its projection area is the largest is 5 to 10 (μm), whose thickness (t) is 1 to 4 (μm), and whose flatness degree d/t expressed by the ratio of the equivalent circle diameter (d) to the thickness (t) is 2 to 8. The ratio of the maximum value to the minimum value of the flatness degree d/t of each toner is 1 to 2.</p> |
