Abstract
A dry toner that is heat-fixable and/or press-fixable is disclosed, comprising (a) a colorant; and (b) a graft copolymer comprising (i) a crystalline polymer having a melting point of from 45.degree. C. to 200.degree. C., which is prepared from one or more monomers selected from ethylene, propylene and vinyl acetate, and (ii) an amorphous polymer having a glass transition point of 45.degree. C. or more, which is prepared from one or more vinyl monomers.
