Abstract (en)
A toner comprising spherical particles obtainable by suspension polymerization which comprise a binder resin and a coloring agent, wherein the median diameter of the particles based on the volume is in the range of from 3 to 20 mu m, the molecular weight distribution of the particles has a plurality of peaks such that the peak of the minimum position in the molecular weight distribution is lower than 50,000 and the peak of the maximum position is higher than 200,000, and processes for its production. The toner has excellent fixing properties, antiblocking properties and offset resistance.
