摘要

A toner having excellent fixing properties and offset resistance comprising a binder resin and a coloring agent obtainable by suspension polymerization, wherein the median diameter D50 of the toner particles based on their volume is in the range of from 3 to 20 mu m, the weight average molecular weight (Mw) of the toner particles is at least 100,000 and the dispersion degree (Mw/Mn) thereof expressed by the ratio of the weight (Mw) to the number average molecular weight (Mn) is at least 50. <IMAGE>
