<p>PROBLEM TO BE SOLVED: To sufficiently improve the performance, such as electrostatic charge performance and flow property, of toners by the sufficient adhesion of additives to the toners of small grain sizes on the toners of high average circularity when such toners are used in manufacturing the toners adhered with the additives on their surfaces by mixing the toners and the additives. SOLUTION: In manufacturing the toners added with the additives on their surfaces by mixing the toners and the additives, the toners and the additives are mixed by setting the temperature T ( deg.C) of the mixture composed of the toners and the additives during mixing so as to attain a temperature range of Tg-20<=T<Tg with respect to the glass transition point Tg ( deg.C) of the resin used for the toners.</p> |
