PROBLEM TO BE SOLVED: To provide a toner that is excellent in both low-temperature fixability and fluidity and has suppressed a reduction in image density even after a long-term use.SOLUTION: A toner contains toner base particles and an external additive adhered to the surface of each of the toner base particles. The toner base particles each include a toner core and a shell layer formed on the surface of the toner core. The hardness of the shell layer is 1.0 N/mor more and 3.0 N/mor less, and the adhesive force of the shell layer to the external additive is 4 nN or more and 10 nN or less.SELECTED DRAWING: None |
