摘要： Disclosed is a method for producing a toner for developing electrostatic images, which comprises the steps of kneading a mixture of raw materials comprising at least a resin and a colorant, cooling the kneaded mixture, pulverizing the cooled mixture, classifying the pulverized mixture, and feeding a fine powder separated by the classification step to a melt of the mixture of raw materials in the middle of the kneading step. The toner has improved fixability, durability and storage stability, with which stable and high-quality images are obtained even by continuous copying operation.
