摘要:
To provide a toner, which contains: a binder resin; a colorant; and wax, wherein the toner has Ta of 30° C. to 55° C., and Tb−Ta of 8° C. to 25° C., where Ta is a glass transition temperature of the toner determined from a constant heating component of a DSC curve of the toner obtained in a second heating process of temperature modulated differential scanning calorimetry, and Tb is a glass transition temperature of the toner determined from a constant heating component of a DSC curve of the toner obtained in a first heating process of temperature modulated differential scanning calorimetry.
