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.
