摘要: The present invention relates to toners for developing electrostatically charged images which contains polyethylene fine particles and polypropylene fine particles as wax, which have a specific particle size. By incorporating such polyethylene and polypropylene fine particles into toners the prevention of smear, offset, filming, and improvement of fluidity and chargeability of the toners can be achieved.

摘要: A toner for full-color development for use in a developing system of a full-color image forming apparatus which comprises a binder resin having a glass transition point Tg of from 60.degree. to 75.degree. C., a number-average molecular weight Mn of from 3500 to 6000, a ratio of a weight-average molecular weight Mw to the number-average molecular weight Mn (Mw/Mn) ranging from 3 to 8, and a difference between a temperature T.sub.1 at the apparent melt viscosity of 1.times.10.sup.5 poise and a temperature T.sub.2 at the apparent melt viscosity of 1.times.10.sup.6 poise DT (=T.sub.1 -t.sub.2) in the range of from 8.degree. to 15.degree. C.
