The toner according to the present invention comprises a vinyl resin which has a wide molecular-weight distribution (Mn:1,000-20,000, Mw: 50,000-2,000,000), a glass transition temperature (Tg) of 40.degree.-75.degree. C. and a low acid value (AV:1-10); and a glycidyl compound in an amount sufficient to provide 0.05-1.0 equivalent of glycidyl groups per equivalent of COOH groups in the vinyl resin. It assures well-balanced fixing property, offset resistance and blocking resistance. In particular, it exhibits a remarkable effect in improving offset resistance and also in grindability during the production of the toner.

The polymer is obtained by mixing 20-80 parts by weight of a low molecular polymer having a number average molecular weight of 1,000-5,000 and a glass transition temperature (Tg) of 40.degree.-75.degree. C., 80-20 parts by weight of a vinyl monomer, 0.01-5 parts by weight of a polymerization initiator and 0-3 parts by weight of a crosslinking agent, dispersing the resultant mixture in an aqueous system and then polymerizing same. The toner resin has excellent low-temperature fixing property and offsetting resistance, can provide marks of superb vividness, and also can prevent modifications of copied marks, for example, due to transfer of a plasticizer.
