PURPOSE:To improve offset resistance, by using a toner contg. polyester, and polyethylene or polypropylene having a specified melt viscosity, and controlling the toner to a specified melt index. CONSTITUTION:A binder resin contains at least 50wt% modified polyester obtained by reacting dicarboxylic acid contg. polyol or polycarboxylic acid with diol; and 0.1-10wt% polyethylene or polypropylene having 10-10<5> centipoises melt viscosity at 140 deg.C to control a toner to 0.01-20g/10min melt index. |
