AbstractA toner particle includes a binder resin, a colorant, a releasing agent, and a dispersant. The binder resin includes a non-crystalline polyester resin containing 1 to 15 mol % of a polyfunctional carboxylic acid unit having a pendant group with 3 to 32 carbons and a crystalline polyester resin. An endothermic amount Tg2nd-dH derived from the crystalline polyester resin is 4 to 40 J/g. The releasing agent has a melting point of 60 to 100° C. The dispersant has a melting point of 60 to 100° C. A mass ratio of the dispersant to the releasing agent is 50:50 to 95:5.
