Toner and method of producing toner

A method of producing a toner that contains a toner particle containing a binder resin and a release agent, the binder resin comprising an amorphous resin and a crystalline resin, a content of the crystalline resin being 1.0 to 20.0% by mass based on a mass of the binder resin, the method comprising the steps of:

• melt-kneading a material containing the amorphous resin, the crystalline resin and the release agent to obtain a melt-kneaded product;
• and
• pulverizing the melt-kneaded product to obtain powder, wherein
• in a cross-section of the toner particle observed by scanning transmission electron microscopy
• (i) there exists a matrix A of the amorphous resin with domains A of the release agent dispersed therein,
• (ii) domains A each include a matrix B of the release agent with domains B of the crystalline resin dispersed therein, and
• (iii) the domains A are each covered with the crystalline resin, and an average coverage of the domains A by the crystalline resin is at least 70%, and
• a melting point difference obtained by subtracting a melting point of the release agent from a melting point of the crystalline resin is 0 to 10° C., and
• a heat-melted crystalline resin composition obtained by separation operation of an N,N-dimethylformamide soluble fraction of the toner particle by a solvent gradient elution method has a visible light transmittance per 1 mm optical path length of at least 90%, the crystalline resin composition comprising a portion constituting domain B and a portion covering domain A.
