| titleOfInvention | Electrophotographic toner and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To define a hardness of a solid obtained by melting and kneading toner raw materials and then cooling and solidifying the solid, so that the solid can be easily pulverized into a small particle size, and a long term. Provided is an electrophotographic toner having excellent stability. SOLUTION: The method for producing an electrophotographic toner according to the present invention is a method for producing an electrophotographic toner by pulverizing a melt-solidified chip-shaped kneaded material after a kneading step, which comprises at least a resin, a pigment and a charge control agent. A method of obtaining a toner, wherein the chip-shaped kneaded material has a micro Vickers hardness of 5 kg / mm 2 or more. In the examples, a predetermined toner raw material mixture was melt-kneaded, and the kneaded material was rolled, cooled, coarsely ground, ground and classified to obtain base colored particles having an average particle diameter of 7 μm. The mother colored particles were mixed with silica differential powder to obtain a toner. The melt-kneading step was performed without evacuation. 10 μm size inside the chip-shaped kneaded material Many of the above voids existed. |
