To provide a toner having excellent low-temperature fixing property, pulverization property during toner production, copy blocking resistance, excellent stress resistance and filming resistance, low cost, and high environmental safety. At least a toner containing a binder resin, the maximum peak height W of a spectrum derived from a bisphenol A skeleton at 1480 to 1520 cm −1 of the toner measured by an ATR method using FT-IR; The GPC determined by the peak ratio (W / R) with the maximum peak height R of the spectrum derived from the carbonyl group at 1700 to 1750 cm −1 being 0.20 to 0.70 and the THF soluble matter in the toner. The toner has a main peak between 1000 and 10,000 in molecular weight distribution, a half width of the distribution is 20,000 or less in molecular weight, and contains 5 to 40% by mass of THF-insoluble matter.
