There is provided a toner which can be manufactured in a simple production
method and which is excellent in preservation stability and anti-offset
property with uniformly-charging performance. The toner is formed of
aggregate of resin-containing particles which are obtained by forming
amorphous resin particles into slurry and further finely granulating the
amorphous resin particles in form of the slurry followed by aggregation
of the amorphous resin particles and which contains a binder resin, a
colorant, a release agent, and a release agent-dispersing aid, the
resin-containing particles having a volume average particle diameter in a
range of from 0.4 .mu.m to 1.0 .mu.m.
