More Information
Summary:A toner including: a binder resin component; crystal nucleating agent; releasing agent; and colorant, wherein the binder resin component contains a crystalline polyester resin and a non-crystalline polyester resin, the crystal nucleating agent is at least one of an aliphatic ester compound and an aliphatic amide compound each having a melting point of 60° C. or higher but lower than 150° C., and wherein the toner satisfies Expressions (I) and (II): Tc>Tp+10  Expression (I) Tm>Tp+2  Expression (II) where Tp denotes lowest exothermic peak temperature [° C.] in 0° C. to 200° C. in DSC curve obtained DSC of the crystalline polyester resin, Tc denotes lowest exothermic peak temperature [° C.] in 0° C. to 200° C. in DSC curve obtained DSC of the crystal nucleating agent, and Tm denotes lowest exothermic peak temperature [° C.] in 0° C. to 200° C. in DSC curve through DSC of the mixture of the crystalline polyester resin and the crystal nucleating agent.
