Magnetic toner and method for manufacturing magnetic toner
Provided is a magnetic toner having a toner particle containing a binder resin and a magnetic body, wherein the binder resin contains a polymer A having a first monomer unit and a second monomer unit, the first polymerizable monomer is at least one selected from the group consisting of the (meth)acrylic acid esters having C18-36 alkyl groups, a content of the first monomer unit and a content of the second monomer unit based on the total moles of all monomer units in the polymer A are respectively 5.0 to 60.0 mol % and 20.0 to 95.0 mol %, and assuming that an SP value of the first monomer unit and the second monomer unit are taken as SP11 (J/cm3)0.5 and SP21(J/cm3)0.5, respectively, 3.00≤(SP21−SP11)≤25.00 is satisfied, and an oil absorption of the magnetic body is 5 to 40 ml/100 g.
