摘要:
The toner of the present disclosure comprises a toner particle containing a crystalline resin A, an amorphous resin B, and a release agent, wherein the resin A contains a specific amount of a unit (a) and is contained in a specific amount in the toner, the resin B is contained in a specific amount in the toner, the total content of the resin A and the resin B is 50.0 mass % or more based on the mass of the toner, when a component W having a molecular weight of 5000 or less is isolated from the toner by a certain procedure, the content of the component W is from 0.5 mass % to 20.0 mass % based on the mass of the toner, and the maximum endothermic peak temperature of the component W and the endothermic peak temperature derived from the component W of the toner satisfy a certain requirement.
