ABSTRACT:
A toner has at least 100 parts by weight of binder resin and 0.1 to 15 parts by weight of colorant. The toner has a number average particle size (Dn) of 0.5 to 6.0 .mu.m, a particle size distribution coefficient (volume average particle size (Dv) / number average particle size (Dn)) of 1.0 to 1.3 and a variation coefficient of particle number distribution of 20% or less.
The toner contains 0.1 to 5.0% by weight of methanol-soluble resin component extracted by the first Soxhlet extraction with methanol and 50 to 99% by weight of THF-soluble resin component extracted by a second Soxhlet extraction with tetrahydrofuran (THF) after the Soxhlet extraction with methanol, wherein the maximum glass transition point (Tg.sub.2) of the methanol-soluble resin component and the glass transition point (Tg.sub.1) of the THF-soluble resin component satisfies the following relation;
