Abstract
A resin particle includes a fluorescent colorant and a color pigment. A hue angle of the resin particle and a hue angle of the fluorescent colorant are different from each other. 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.
