Toner

A toner, comprising a toner particle, the toner particle having a core-shell structure comprising:

• a core containing a core resin, a colorant, and a wax;
• a shell layer containing a resin “A” on a surface of the core, the resin “A” containing a segment having an organopolysiloxane structure and being a polymer of a monomer composition comprising a monomer “a” having two or more polymerizable unsaturated groups in one molecule thereof, the monomer “a” satisfying (Xa−1.0)×Ya≧3.0×10-5 where Xa represents an average number of polymerizable unsaturated groups in one molecule of monomer “a”, and Ya represents a number of moles (mol/g) of monomer “a” with respect to a total mass of all monomers in the monomer composition;
• and
• between the core and the shell layer, an intermediate layer containing a resin “B”, the resin “B” containing a segment having an organopolysiloxane structure and being a polymer of a monomer composition containing a monomer “b” having two or more polymerizable unsaturated groups in one molecule thereof, wherein
• the toner particle has an amount of Si (atomic %) derived from the organopolysiloxane structure of resin “A” of 6.0 to 10.0 measured by X-ray photoelectron spectroscopy (ESCA),
• resin “A” and resin “B” satisfy Za>Zb, where Za represents an amount of Si of the resin “A” measured by fluorescent X-ray analysis (XRF), and Zb represents an amount of Si of the resin “B” measured by fluorescent X-ray analysis (XRF), and
• resin “A” and resin “B” further satisfy (Xa−1.0)×Ya≧(Xb−1.0)×Yb, where Xb represents an average number of polymerizable unsaturated groups in one molecule of monomer “b” in resin “B”, and Yb represents a number of moles (mol/g) of monomer “b” with respect to a total mass of all monomers in the monomer composition in resin “B”.
