Zusammenfassung:A yellow toner including a toner particle including a binder resin, a crystalline resin, and C.I. Pigment Yellow 180, a content of the C.I. Pigment Yellow 180 is 3% by mass or more and 15% by mass or less with respect to a mass of the toner, the C.I. Pigment Yellow 180 is in a form of plate-like particles each having a plate-like shape, and when the C.I. Pigment Yellow 180 is observed with a scanning electron microscope, the plate-like particles of the C.I. Pigment Yellow 180 satisfy the following relationships: S/Z≥10.0; and 50≤S≤300, where the S (nm) represents a number average of circle-equivalent diameters calculated from areas of surfaces having largest areas of the plate-like particles, and the Z (nm) represents a number average of widths in directions perpendicular to the surfaces having the largest areas of the plate-like particles.
