    • A toner, including: crystalline resin; non-crystalline resin; and a composite resin, wherein the crystalline resin is crystalline polyester resin (A), the non-crystalline resin comprises: non-crystalline resin (B) containing chloroform insoluble matter; and non-crystalline resin (C) having a softening temperature (T½) lower than that of the non-crystalline resin (B) by 25° C. or more, an absolute value |Tgc−Tgb| of a difference between a glass transition temperature (Tgc) of non-crystalline resin (C) and a glass transition temperature (Tgb) of non-crystalline resin (B) is 10° C. or lower, wherein the composite resin is composite resin (D) containing a condensation polymerization resin unit and an addition polymerization resin unit, and the toner has a molecular weight distribution having a main peak in 1,000 to 10,000 and a half width of 15,000 or less, where the molecular weight distribution is obtained by gel permeation chromatography (GPC) of tetrahydrofuran (THF) soluble matter of the toner.
