PURPOSE:To provide a toner for electrophotography by sticking specified carbon particles on the surface of a polymerized toner of small particle size so as to obtain many copied images having high resolution as well as to reduce the dependency of the toner used for a two-component developer on the environment. CONSTITUTION:Carbon black of >=30mum average particle size having 100ml/100g oil absorption is stuck to the surfaces of toner particles of 3-8mum average particle size produced by polymn. by 0.05-1 pt.wt. per 100 pts.wt. of the toner particles to obtain a toner for electrophotography. |
