Abstract
Toner particles each include a toner core, a shell layer covering a surface of the toner core, and a plurality of wax particles. The toner core contains a binder resin and does not contain a wax. The wax particles are each located on a surface of the shell layer. The toner core and each of the wax particles are bonded together through covalent bonds within the shell layer. The covalent bonds include a first amide bond and a second amide bond. The shell layer contains a vinyl resin. The vinyl resin includes a constitutional unit (1-1), a constitutional unit (1-2), and a constitutional unit (1-3). An amide bond included in the constitutional unit (1-1) is the first amide bond. An amide bond included in the constitutional unit (1-2) is the second amide bond.
