Toner and method for producing toner

A toner comprising a toner particle including a binder resin, wherein the binder resin includes a polymer A,

• the polymer A is a polymer of a composition including:
• a first polymerizable monomer, and
• a second polymerizable monomer different from the first polymerizable monomer;
• the first polymerizable monomer is at least one selected from the group consisting of (meth)acrylic acid esters having an alkyl group having 18 to 36 carbon atoms;
• a content of the first polymerizable monomer in the composition is 5.0 mol % to 60.0 mol %, based on the total number of moles of all the polymerizable monomers in the composition;
• a content of the second polymerizable monomer in the composition is 20.0 mol % to 95.0 mol %, based on the total number of moles of all the polymerizable monomers in the composition;
• where an SP value of the first polymerizable monomer is denoted by SP12 (J/cm3)0.5 and an SP value of the second polymerizable monomer is denoted by SP22 (J/cm3)0.5, following formulas (4) and (5) are satisfied;
• the polymer A includes a polyvalent metal;
• the polyvalent metal is at least one selected from the group consisting of Mg, Ca, Al, and Zn;
• and
• a content of the polyvalent metal in the toner particle is 25 ppm to 500 ppm on a mass basis,
• 0.60≤(SP22−SP12)≤15.00 (4), and
• 18.30≤SP22 (5).

A method for producing a toner, comprising:

• a step of preparing a resin fine particle-dispersed solution including a binder resin;
• a step of adding a flocculant to the resin fine particle-dispersed solution to form aggregated particles;
• and
• a step of heating and fusing the aggregated particles to obtain a dispersion solution including toner particles, wherein
• the binder resin includes a polymer A,
• the polymer A is a polymer of a composition including:
• a first polymerizable monomer, and
• a second polymerizable monomer different from the first polymerizable monomer;
• the first polymerizable monomer is at least one selected from the group consisting of (meth)acrylic acid esters having an alkyl group having 18 to 36 carbon atoms;
