Abstract:
Toner particles each include a toner mother particle and an external additive. The toner mother particle includes a toner core containing a binder resin and a shell layer covering a surface of the toner core. The external additive includes a plurality of external addition resin particles. The external addition resin particles are each present on a surface of the shell layer. The shell layer contains a specific vinyl resin. The toner core and each resin particle are bonded together through a covalent bond within the shell layer. A detachment rate of the resin particles is lower than 5%.

Claim (Index 1):
A toner comprising a plurality of toner particles, the toner being positively chargeable, wherein\n the toner particles each include a toner mother particle and an external additive, the toner mother particle includes a toner core containing a binder resin and a shell layer covering a surface of the toner core, the external additive includes a plurality of resin particles containing a resin, the resin particles are each present on a surface of the shell layer, the shell layer contains a vinyl resin, the vinyl resin includes a constitutional unit represented by a formula (1-1) shown below, a constitutional unit represented by a formula (1-2) shown below, and a constitutional unit represented by a formula (1-3) shown below, an atomic group X 1  included in the constitutional unit represented by the formula (1-1) and an atomic group X 2  included in the constitutional unit represented by the formula (1-2) are each derived from an N-methylol group and represented by \u2014NHCH 2 O\u2014, an available bond of an oxygen atom located at a terminal of the atomic group X 1  is connected to an atom constituting the binder resin, an available bond of an oxygen atom located at a terminal of the atomic group X 2  is connected to an atom constituting the resin contained in the resin particles, the toner core and each of the resin particles are bonded together through a covalent bond within the shell layer, the covalent bond includes the atomic group X 1  and the atomic groupX 2 , and a detachment rate of the resin particles from the toner mother particles measured after irradiation of the toner with ultrasonic waves having a high-frequency output of 100 W and an oscillation frequency of 50 kHz for 10 minutes is lower than 5%, where in the formula (1-1), R 1  represents a hydrogen atom or an alkyl group optionally substituted with a substituent, in the formula (1-2), R 2  represents a hydrogen atom or an alkyl group optionally substituted with a substituent, and in the formula (1-3), R 3  and R 4  each represent, independently of each other, a hydrogen atom or an alkyl group optionally substituted with a substituent.
