TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE, ELECTROSTATIC CHARGE IMAGE DEVELOPER, TONER CARTRIDGE, AND PROCESS CARTRIDGE
A toner for developing an electrostatic charge image contains toner particles containing an amorphous resin and a crystalline resin. The ratio Qs1/Qf1 is 1.1 or more and 2.0 or less, where Qf1 is the total area of all endothermic peaks detected during the first temperature rise when the toner partic...

| Zusammenfassung: | A toner for developing an electrostatic charge image contains toner particles containing an amorphous resin and a crystalline resin. The ratio Qs1/Qf1 is 1.1 or more and 2.0 or less, where Qf1 is the total area of all endothermic peaks detected during the first temperature rise when the toner particles are analyzed by differential scanning calorimetry after one-day storage under 50°C conditions, and Qs1 is the total area of all endothermic peaks detected during the first temperature rise when classified toner particles are analyzed by differential scanning calorimetry after one-day storage under 50°C conditions. The classified toner particles are a fraction of the toner particles in which toner particles having a diameter equal to or larger than the volume-average diameter D50v of the toner particles constitute 10% by number or less. |
