Method of producing toner |
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. |
