<p>PROBLEM TO BE SOLVED: To provide color toners of a small grain size which are little in the occurrence of the transfer unevenness and drop-outs of solid images, the transfer dust of fine line parts, the transfer drop-outs in the fine line parts and furhter, surface staining and filming, in the color toners. SOLUTION: The weight average diameter D4 and the image density D0.6 after fixing at 0.60 mg/cm2 in the deposition of the toner on a transfer material of the color toners, which are formed by adding additives to base material toners consisting of at least a binder resin and coloring agent and have the weight verge diameter D4 of 5.0 to 9.0μm, satisfy the following equation (1). In addition, the plus sieve residual amount after sieving of 100 g toners with a sieve of 500 mesh is <=10 mg. D0.6=-0.15D4+k...(1) (2.3<=k<=3.3).</p> |
