Abstract: A yellow toner is provided. The yellow toner comprises toner particles each comprising a binder resin and a colorant, and 1.0% to 15.0% by number of the toner particles have a CH rate of 25.0% or more in absolute value. Here, the CH rate is calculated from the following formula (1): CH rate (%)=[(In−Iave)/Iave]×100 Formula (1) where In represents an integrated intensity within a wavenumber region of from 2,750 to 3,250 cm−1 when an intensity at a wavenumber λ within a wavenumber region of from 950 to 3,250 cm−1 is normalized to 1 in a Raman spectrum of each toner particle; and Iave represents an average of the In.
