Abstract
Toner particles each have a toner core, a shell layer covering a surface of the toner core, and first resin particles containing a melamine resin. A shell layer coverage is 60% to 80%. The first resin particles each have an embedded portion and a protrusion portion. The embedded portions are embedded beneath the surface of the toner core. The protrusion portions protrude outward from the surface of the toner core in a radial direction of the toner particle. An average value Wd of thicknesses b of the shell layers, a number average value Dp of embedment depths c of the first resin particles, and a number average value Pd of primary particle diameters d of the first resin particles satisfy relations (1) to (3) shown below.0.2≤≤0.8  (1)()>  (2)0.10 μm≤≤1.00 μm  (3)
