Abstract:
A heat-fixable developer for electrophotography, comprising a binder resin (A), a colorant (B) and a releasing agent (C),wherein the releasing agent (C) comprises at least one ethylene/aromatic vinyl compound random copolymer revealing no peak in the .sup.13 C-NMR spectrum due to aromatic vinyl compound-to-aromatic vinyl compound chain block, wherein the copolymer is selected from the group consisting of copolymer i) and copolymer ii),the copolymer i) being an ethylene/aromatic vinyl compound copolymer obtained by co-polymerizing ethylene and an aromatic vinyl compound in the presence of a metallocene catalyst (D) andthe copolymer ii) being an ethylene/aromatic vinyl compound copolymer obtained by a heat-degradation of a copolymer produced by co-polymerizing ethylene and an aromatic vinyl compound in the presence of a metallocene catalyst (D).
