Abstract
A toner has a toner particle containing a binder resin having a first resin and a second resin. The first resin is a crystalline resin, the second resin is an amorphous resin, and the first resin has a first monomer unit, a second monomer unit and a third monomer unit, each having a specific structure. A content of the first monomer unit a content of the third monomer unit in the first resin, and an SP value of the second monomer unit all satisfy a specific ranges, and the second resin contains at least one vinyl-based resin and/or specific hybrid resin, with a cross section of the toner having a domain-matrix structure formed of a matrix including the first resin and domains including the second resin, a number average diameter of the domains being 0.10 to 2.00 μm.
