摘要： In accordance with the present invention, the electrophotographic toner is produced by dispersing and mixing toner components containing a fixing resin, a coloring agent and an electric charge controlling dye, and by melting and kneading the resulting mixture, which is then subjected to pulverizing and classifying. According to the present invention, fine powder generated at the pulverizing and classifying steps is reused as added to a mixture of toner components as already dispersed and mixed at the dispersing and mixing step, and the surface dye density of the electric charge controlling dye is in the range from 1.0 x 10⁻³ to 1.7 x 10⁻³ g/g, or the rate of the amount of an electric charge controlling dye present on the surfaces of toner particles to the total amount of the electric charge controlling dye, is in the range from 10 to 27 % by weight. Even though repeatedly used for a long period of time, the electrophotographic toner does not lower the developer in electric charging characteristics. Further, by adding the fine powder to the mixture as already dispersed and mixed at the dispersing and mixing step, there can be efficiently produced a fine-powder regenerated toner excellent in transfer efficiency, resolution and gradation.
摘要翻译：根据本发明，电子照相调色剂通过将包含固定树脂，着色剂和电荷控制染料的调色剂组分分散和混合并通过熔融和捏合所得混合物来制备，然后对其进行粉碎和分级。根据本发明，在粉碎和分级步骤中产生的细粉末在分散混合步骤中已经分散和混合的调色剂组分的混合物中被重新使用，并且电荷控制染料的表面染料密度在 3.0×10 -3至1.7×10 -3 g / g的范围，或者调色剂颗粒表面上存在的电荷控制染料的量相对于电荷控制染料的重量在10〜27％的范围内。即使重复使用了很长一段时间，电子照相调色剂也不会使显影剂的充电特性降低。此外，通过在分散混合步骤中已经分散和混合的混合物中加入细粉，可以有效地生产转印效率，分辨率和灰度优异的细粉再生调色剂。
