Abstract

<div notation="docdba" type="abstract" xml:lang="en"><p>A toner, including a toner particle that contains a binder resin and a release agent, wherein the binder resin contains a polymer A, the polymer A including a first monomer unit derived from a first polymerizable monomer and a second monomer unit derived from a second polymerizable monomer different from the first polymerizable monomer; the first polymerizable monomer is selected from (meth)acrylic acid esters having a C&lt;sub>18-36&lt;/sub>alkyl group; the toner has a first monomer unit content and a second monomer unit content in the polymer A which are within specific ranges, and assuming that an SP value of the first monomer unit is taken as SP&lt;sub>11&lt;/sub>and an SP value of the second monomer unit is taken as SP&lt;sub>21&lt;/sub>, the formula (1) below is satisfied, and the molecular weight of the release agent is at least 1,000.3.00≤SP21−SP11≤25.00</p></div>
