Toner

A toner comprising a toner particle comprising a binder resin, wherein

• the binder resin comprises a crystalline resin and an amorphous resin,
• the crystalline resin comprises a crystalline vinyl resin having a monomer unit (a) represented by Formula (1) below,
• in differential scanning calorimetry (DSC) using the toner as a sample, a melting point peak derived from the crystalline vinyl resin is observed in a range of 50.0 to 80.0° C.,
• when a cross section of the toner is observed under a scanning transmission electron microscope,
• (i) a phase-separated structure having a crystalline phase comprising the crystalline resin as a main component and an amorphous phase comprising the amorphous resin as a main component is present in the cross section of the toner particle,
• (ii) when the region from the surface of the toner particle up to 700 nm into the toner particle is defined as a region A, and the region from the surface of the toner particle up to 200 nm into the toner particle is defined as a region B, within the amorphous phase present in the entire cross-section of the toner particle, at least 60 area % of the amorphous phase is present in the region A,
• an area proportion of the amorphous phase in the region A is 45 to 90 area %,
• an area proportion of the crystalline phase in the region B is 5 to 40 area %:
• in Formula (1), R1 is a hydrogen atom or a methyl group, n is an integer of 15 to 35.
