摘要： A toner which has i) toner base particles containing at least a binder resin and a colorant and ii) a fatty acid metal salt composition as an external additive. The fatty acid metal salt composition contains a nonionic surface-active agent and a fatty acid metal salt. This toner and an image forming process making use of the toner can keep the toner from adhering to a toner carrying member throughout running, promise a stable chargeability of the toner and can keep any deterioration of halftone image quality from being caused by excess charging of the toner and any image fog from being caused by insufficient charging of the 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.
