To provide a toner having excellent low-temperature fixability, high-temperature offset resistance, heat-resistant storage stability, and toner image blocking resistance after fixing, and a developer containing the toner. A toner comprising a binder resin component, a release agent, and a colorant, The binder resin component contains a crystalline polyester resin and an amorphous polyester resin, and an aromatic phosphate metal salt having a higher melting point than the crystalline polyester, In differential scanning calorimetry (DSC) when the temperature is lowered from 150 ° C. to 0 ° C., the lowest exothermic peak temperature of the crystalline polyester is Tp [° C.], and the crystalline polyester and the aromatic phosphate metal salt A toner wherein the relationship between Tp and Tm satisfies the following formula (I) when the lowest exothermic peak temperature of the mixture is Tm [° C.].
