Abstract
A toner includes toner particles. The toner particles each include a toner core, silica particles located on a surface of the toner core, and a shell layer disposed over the surface of the toner core on which the silica particles are located. For at least 80% by number of the toner particles, along at least 80% of a circumferential length of a cross-section of the toner particle when the cross-section is analyzed by EELS, the shell layer has a thickness of at least 5 nm and satisfies a condition that a ratio of an intensity INc relative to an intensity INs is at least 0.0 and no greater than 0.2. The intensity INs indicates intensity of an N—K shell absorption-edge originating from nitrogen atoms in the shell layer. The intensity INc indicates intensity of an N—K shell absorption-edge originating from nitrogen atoms in the toner core.
