Abstract

PURPOSE:To accelerate the fixing, prevent offset without using an offset preventing liq. and enhance the triboelectric charging properties, etc. by using a graft copolymer of a specified crystalline polymer and a specified amorphous vinyl polymer as a binding resin. CONSTITUTION:An amorphous polymer having >=45 deg.C glass transition point and obtd. using >=1 kinds of vinyl monomers such as styrene and methacrylate is grafted on a crystalline polymer having 45-200 deg.C m.p. and obtd. using >=1 kinds of monomers selected from ethylene, propylene and vinyl acetate to prepare a copolymer contg. said crystalline polymer by 1-30wt% to the amount of the copolymer. This graft copolymer is used as a binding resin for a toner. Thus, no toner coat is formed on a photoreceptor, a carrier is not polluted, and the blocking of toner particles is prevented.
