A toner has been developed having low energy fusibility, high durability and high stability of charge characteristics for high speed non-magnetic mono-component process. This toner is applicable in printing speeds up to 45ppm in an electrophotographic printer, by improving the durability of the toner. The improvement was carried out by reducing the low molecular weight component without raising the thermal characteristics of toner resin, improving the dispersion of additives in toner resin and round-edging the toner shape. This toner is also suitable for application in printings with speeds down to 12ppm because of the improved stability of the charge characteristics and the reduced background fog.
