摘要：
The foregoing problem is solved with a toner for the development of an electrostatic image obtained by externally adding agglomerated particles to toner particles containing a binder resin and a colorant, characterized in that the agglomerated particles are made of (i) a particulate resin alone, (ii) a particulate lubricant alone or (iii) at least two particulate materials selected from the group consisting of particulate resin, particulate lubricant and inorganic particulate material and have a shape factor of 130 or more and a volume-average particle diameter of from 0.5 &mgr;m to 10 &mgr;m.
