摘要:
In a chart of molecular weight distribution measured of a toner, i) the toner has a main peak in the region of molecular weight of 16,000 to 60,000, and ii) where the molecular weight at the main peak is represented by M1, and where the height at the molecular weight M1 is represented by H(M1), the height at a molecular weight of 4,000 by H(4000) and the height at a molecular weight of 15,000 by H(15000), the H(4000), the H(15000) and the H(M1) satisfy a specific proportion. The toner has a weight-average molecular weight (Mw) of 15,000 to 80,000, and, in an endothermic chart, i) the toner has an endothermic main peak in the range of 40 to 130° C., and ii) the calorimetric integral value represented by the peak area of the endothermic main peak is 10 to 35 J per 1 g of the toner.
