摘要： A method of stably producing a toner is provided. This method provides a long-term stabilization of material dispersion in a colorant-dispersed solution and inhibits segregation of the material and provides a more microfine and more uniform dispersion of the colorant in the toner, and moreover produces a toner that has a sharp toner particle diameter distribution. This method of producing toner has at least a colorant dispersion step of obtaining a colorant-dispersed solution by dispersing a pigment-containing colorant in a liquid mixture that contains the colorant and a dissolved resin solution or a polymerizable monomer, wherein the liquid mixture contains a nonionic surfactant and the nonionic surfactant has at least an oxyalkylene group and has a hydrophile-lipophile balance value (HLB value) of 9.0 or more and 17.0 or less.

摘要： A toner is provided that exhibits a high long-term image stability even during high-speed printing and that also exhibits an excellent environmental stability. The toner comprises a binder resin, a colorant, and a nonionic surfactant, wherein the nonionic surfactant has an oxyethylene group (EO) and an oxypropylene group (PO) and has a ratio of the number of moles of the oxypropylene group to the number of moles of the oxyethylene group (PO/EO) of at least 0.01 and not more than 5.00; and when A (μg/g) is defined as a nonionic surfactant content on the surface of the toner that can be extracted by methanol from 1 g of the toner and B (m2/g) is defined as a theoretical specific surface area determined from a toner particle diameter distribution obtained by a precision particle diameter distribution analyzer that operates based on an aperture electrical resistance method, a ratio A/B is at least 100 μg/m2 and not more than 9000 μg/m2.
