Toner is a key component for high-speed and high-quality color laser printing. However, pre-developed pulverized toner has unresolved problems such as a high cost, limitations of the variance in the process of melting and mixing internal additives, and low printing quality. Polymerized toners are being developed to solve the problems of pulverized toner and make high-speed and high-quality color laser printing possible. In this study, polymerized toner was prepared using hydroxyapatite as a suspending agent. The effects of the suspending agent on the characteristics of the polymerized toner were studied. Hydroxyapatite prepared at different Ca/P ratios affected largely the shape of polymerized toner particles and the physical properties of the polymerized toner. Moreover, the polymerization of toner particles was considerably affected by pH. We found a large possibility that high-quality polymerized toner could be prepared using hydroxyapatite at an optimized Ca/P ratio and pH. |
