TONER COATED WITH THIN-FILM

摘要

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 the heat energy and time required for fixing, leading to energy saving and speed-up in a fixing step.
