摘要:
The present invention provides a toner including a toner particle containing a binder resin and a release agent. The binder resin contains an amorphous resin and a crystalline resin, and a content of the crystalline resin is 1.0% to 20.0% by mass based on a mass of the binder resin. In a cross-section of the toner particle observed by scanning transmission electron microscopy, (i) there exist a matrix A of the amorphous resin and domains A of the release agent dispersed in the matrix A, (ii) the domains A each include a matrix B of the release agent and domains B of the crystalline resin dispersed in the matrix B, 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 70% or more.
