Claim 0:
1. A resin particle comprising:
a resin;
a fluorescent colorant; and
a color pigment, wherein
a hue angle of the resin particle and a hue angle of the fluorescent colorant are different from each other, and
when a fluorescence peak wavelength in a spectral reflectance of the fluorescent colorant is represented by A (nm), an integrated value of a spectral reflectance (%) of the color pigment in a wavelength range of from A−30 (nm) to A+30 (nm) is 2,500 or more,
wherein a content of the color pigment is 0.05% by mass or more and 1.5% by mass or less based on the total mass of the resin particle,
wherein a content of the fluorescent colorant is 0.1% by mass or more and 3.5% by mass or less based on a total mass of the resin particle,
wherein the fluorescent colorant includes at least one compound having a xanthene structure, and the color pigment is a compound having a quinacridone structure, and wherein the at least one compound having a xanthene structure is a compound having a rhodamine structure, a fluorescein structure, or an eosin structure.
