Abstract
A toner includes toner particles. The toner particles each include a composite core and a shell layer covering a surface of the composite core. The composite core is a composite of a toner core and organic particles located on a surface of the toner core. The toner core contains a releasing agent having a carboxyl group. The organic particles contain a resin having a carboxyl group and a mass average molecular weight of from 30,000 to 50,500. The shell layer includes a unit having a non-ring-opened oxazoline group. An amount of the non-ring-opened oxazoline group contained in 1 g of the toner as measured by gas chromatography-mass spectrometry is from 500 μmol to 1,400 μmol. An endothermic quantity due to melting of the releasing agent contained in 1 mg of the toner as measured by differential scanning calorimetry is from 80 mJ to 160 mJ.
