Provided is a toner having excellent low-temperature fixability, capable of obtaining a sufficient image density even with a small amount, and having no image damage such as fogging in a high-temperature and high-humidity environment even when used for a long time. A toner having toner particles containing a binder resin, a pigment, a pigment dispersant, and a crystalline polyester, wherein the binder resin is an amorphous polyester resin, and the pigment dispersant is: Toner satisfying (i) to (iv): (I) The difference (A−B) between the SP value (A) of the pigment dispersant and the SP value (B) of the crystalline polyester resin is −0.90 or more and +1.00 or less, (Ii) The difference (A−C) between the SP value (A) of the pigment dispersant and the SP value (C) of the binder resin is −2.00 or more and +2.00 or less, (Iii) The pigment dispersant has a polymer component and an adsorption component having an adsorption rate of 30% or more to the pigment, and the polymer component has a partial structure represented by a vinyl polymer, (Iv) The number average molecular weight (Mn) of the polymer component of the pigment dispersant is 3000 to 20000.
