Process for making magnetic toners

Abstract

A magnetic toner comprising a binder resin a magnetic substance is disclosed, the toner containing from 2 to 20% by weight of a polyolefin, preferably polyethylene, having a dispersed particle size of from 0.01 to 0.5 .mu.m. The particle size distribution of the polyolefin preferably has a coefficient of variation of from 20 to 40%. The magnetic toner is fixable with low heat energy, hardly causes offset and smudge, and has a reduced abrasive action on a photoreceptor. It is therefore suitable for use in a fixing means with no cleaning mechanism, a machine with a double side copying function, or an organic photoreceptor.
