[PROBLEMS] To provide a sharp particle size distribution, good toner characteristics such as charging property, environmental property, stability over time, low cost, no waste liquid, no drying process, and residual monomer. Provided are a toner production method that does not contain and has a low environmental load, and a toner produced by the toner production method. A toner is granulated by polymerizing at least a polymerizable monomer in at least one of a supercritical fluid and a subcritical fluid, and at least one of the supercritical fluid and the subcritical fluid has a fluorine-based surface activity. And a toner produced by the production method, wherein the polymerized polymer of the polymerizable monomer is insoluble in at least one of the supercritical fluid and the subcritical fluid.
