To provide a toner having both heat-resistant storage stability and low-temperature fixability, excellent durability stability, a small particle size, and a uniform shape with a sharp particle size distribution and circularity distribution. Capsule-type toner particles having a surface layer containing a urethane resin as a main component on the surface of toner base particles containing at least a resin containing a polyester as a main component, a colorant, and a wax. Has a surface layer of 2.0 parts by weight or more and 15.0 parts by weight or less with respect to 100 parts by weight of toner base particles, and the temperature rise rate is 0.5 ° C. in the measurement with a differential scanning calorimeter (DSC) of toner particles. When the glass transition temperature measured at / min is Tg (0.5) and the glass transition temperature measured at a heating rate of 4.0 ° C./min is Tg (4.0), Tg (0. 5. A toner having 5) of 40 ° C. or more and 60 ° C. or less and Tg (4.0) −Tg (0.5) of 2.0 ° C. or more and 10.0 ° C. or less. [Selection figure] None |
