As color printer becomes to be widely used, demand for fine image quality is also increasing. Therefore, toner with small and narrow size distribution for high-resolution development and small adhesion force to photoconductor for faithful transfer is required.In this paper, design of pulverized toner with small and narrow particle size distribution for oil-less fusing system is reported. To pulverize toner to small size, the combination of fine wax dispersion and pre-condition method, or the pulverization in the existence of silica is important. This advanced pulverized toner using polyester resin also shows low-temperature fusing property, glossy image and fine durability. And an approach to the toner having small adhesion force to photoconductor is also reported. Both of control of the shape of toner and surface treatment by proper silica is effective.
