Abstract
A toner including a toner particle that contains a binder resin and inorganic fine particles, wherein the binder resin contains a polymer A that includes a first monomer unit derived from a first polymerizable monomer and a second monomer unit derived from a second polymerizable monomer that is different from the first polymerizable monomer; the first polymerizable monomer is at least one selected from the group consisting of (meth)acrylate esters having an alkyl group having 18 to 36 carbons; the SP value of the first monomer unit and the SP value of the second monomer unit satisfy a specified relationship; each of the inorganic fine particles contains a substrate containing at least one inorganic element selected from metal elements and metalloid elements, and a coating layer; and the coating layer has a specified structure.
