PURPOSE:To improve the fixability of a copying machine and to prevent the staining of copies by incorporating a specific ratio of an ethylene/methyl methacrylate copolymer resin into the toner. CONSTITUTION:The ethylene/methyl methacrylate copolymer resin is incorporated into the toner essentially consisting of a binder resin and coloring agent at 1 to 30wt.% of the entire part. The ethylene/methyl methacrylate copolymer has resilience and flexibility and the toner contg. 1 to 30wt.% this copolymer has good fixing strength and excellent double face copying property and does not generate staining in an automatic document feeder. The preservable stability and fixability of the toner are compatibly obtd. in this way and the continuous copying is possible. |
