A cyan toner is provided. The cyan toner comprises toner particles each comprising a binder resin and a colorant. From 1.0% to 20.0% by number of the toner particles have a CH rate of 7.0% or more in absolute value. The CH rate is calculated from the following formula (1):

CH rate (%)=[(In−Iave)/Iave]×100  Formula (1)

where, in a Raman spectrum of each toner particle, In represents an integrated intensity within a wavenumber region of from 2,600 to 3,180 cm−1 when an intensity at a wavenumber λ within a wavenumber region of from 2,600 to 2,800 cm−1 is s normalized to 1, where a total intensity of all the toner particles is maximum at the wavenumber λ; and Iave represents an average of the In.
