Abstract
A toner for electrostatic image developing is disclosed. It is prepared by giving a mechanical impact force to radically polymerized particles containing a colorant and a low molecular weight polyolefine so as to have the low molecular weight polyolefine exist at a ratio of 5 to 40% by number on a surface of the particles. The toner has a uniform and good electrification property, high fixability and no offsetting property.
