Toner

A toner comprising a toner particle that comprises a binder resin,

• the binder resin comprising a crystalline vinyl resin and an amorphous resin;
• the amorphous resin comprising an amorphous polyester resin;
• the toner particle being covered with the amorphous polyester resin;
• the crystalline vinyl resin comprising a monomer unit (A) represented by formula (A) below:
• in formula (A), R1 represents a hydrogen atom or a methyl group;
• when an SP value of the crystalline vinyl resin is taken as SP(A) [(J/cm3)0.5], the SP(A) is from 19.0 to 22.5 (J/cm3)0.5;
• and
• in a chart with an x-axis representing time and a y-axis representing ion amounts corresponding to the monomer unit (A), obtained by analyzing the toner particle while performing sputtering up to a sputtering time to remove 20 nm of a polymethyl methacrylate standard sample film in a time-of-flight secondary ion mass spectrometry (TOF-SIMS) using the toner particle as a sample,
• when a maximum value of the ion amount is taken as A(max) and a minimum value of the ion amount is taken as A (min), the A(max) and the A (min) satisfy expression (1) below.
