Abstract:
A toner comprising a binder resin, a colorant and a wax, the toner having a THF soluble component, as analyzed by gel permeation chromatography, the THF soluble component having a number-average molecular weight falling approximately between 2500 and 5500, a weight-average molecular weight falling approximately between 13000 and 25000, and a peak molecular weight falling approximately between 5000 and 15000, the THF soluble component having a component of molecular weight of at least approximately 10.sup.5 in a ratio of at most approximately 10% by weight of the THF soluble component and having a component of molecular weight of at least approximately 10.sup.4 in a ratio of approximately from 30 to 70% by weight of the THF soluble component, and the wax having a DSC endothermic peak falling approximately between 50 and 120.degree.
