PURPOSE:To obtain a toner for electrophotography having superior fixability, anti-offsetting property and image characteristics. CONSTITUTION:This toner compsn. for electrophotography contains a binder and a colorant or further contains low molecular wax by 0.5-20 pts.wt. per 100 pts.wt. of the binder. The binder is based on a resin mixture obtd. by removing the solvent by heating from a resin soln. contg. styrene-based resin and further contg. a block copolymer of blocks of ethylenic hydrocarbon and/or conjugated diene-based hydrocarbon with styrene and/or a hydrogenated body of the copolymer by 0.1-20 pts.wt. per 100 pts.wt. of the styrene-based resin. The low molecular wax may be incorporated into the binder. |
