<p>PROBLEM TO BE SOLVED: To make such a color image formable that is excellent in glossiness and color reproducibility obtained when an image formed on a polyester-made transparent(OHP) sheet is projected by specifying the center-line average inclination of the surface roughness of image when a color image is formed by color toner. SOLUTION: The surface roughness of the image formed on the OHP sheet by a color toner including at least a binder resin, colorant and electrifying control agent is set so as to be 0.2<Ra<=3.0 by defining the center-line average inclination as (Ra). In such a case, the value of (Ra) is obtained by measuring the surface of the image formed on the OHP sheet according to JIS BO601 by using a Surfcom surface roughness tester. Then, when the surface roughness thereof is set to be 0.2<Ra<=3.0, preferably, 0.2<Ra<0.6 by defining the center- line average roughness as (Ra), fixation and anti-offset property are satisfied and, and the same time, the color of the image formed on the OHP sheet is faithfully reproduced as it is when it is projected. Besides, the glossiness is also made excellent when the image is formed on a paper.</p> |
