PURPOSE:To enhance rubbing fixability by incorporating Fischer-Tropsch wax and polypropylene. CONSTITUTION:The Fischer-Tropsch wax and polypropylene are added into the electrostatic charge image developing toner containing a colorant and a binder resin composed essentially of a styrene-acrylic copolymer obtained by mixing a low molecular weight component with a high molecular weight component, thus permitting fixability to satisfy both of a pressed stroke test and a rubbing test and offset resistances in both of high temperature range and low temperature range to be enhanced. |
