PROBLEM TO BE SOLVED: To provide toner excellent in charging characteristics and having a uniform shape and a narrow particle size distribution, and also to provide a toner manufacturing method and a toner manufacturing apparatus by which such toner is efficiently manufactured in an environmentally friendly way. SOLUTION: The toner manufacturing method uses a dispersion in which a dispersoid containing a resin material is dispersed in a dispersion medium and which contains a dispersant having a function of improving the dispersibility of the dispersoid. The resin material consists mainly of a polyester resin, the dispersant has a molecular structure with at least one partial structure selected from the group consisting of a benzene ring (including a substituted benzene ring), a carboxyl group, an ester group, a carbonyl group, an aldehyde group, an amide group, an amino group, an ammonium group, a hydroxyl group and a nitrile group, and after discharging the dispersion as a liquid drop-like discharge, this discharge is irradiated with ultraviolet rays.
