Abstract:
Satisfactory anti-blocking property of powder toner can be realized, while avoiding increase in softening temperature of the powder toner, by coating the surface of a low melting point powder toner with a thermosetting resin. This leads to the realization of toner fixing at lower temperatures and is particularly effective when using a urea resin as the thermosetting resin or employing polymerized toner as the powder toner. Use of the surface-coated powder toner with a low softening temperature and less blocking tendency makes possible reduction of thermal energy and time required for fusing, thereby realizing energy-saving and high-speed fusing process.

Abstract:
A low melting point powder toner the surface of which is coated with a thermosetting resin. The powder toner allows the achievement of satisfactory anti-blocking property with no elevation of the softening temperature, resulting in fixing at a low temperature. Such an effect is markedly significant in particular when the thermoplastic resin is a urea based resin and when the powder toner is a polymerization toner. The use of the above surface coated toner having a low softening temperature and low blocking tendency results in low temperature fixing, which allows the reduction of th e heat energy and time required for fixing, leading to energy saving and speed - up in a fixing step.
