This report is a summary of full color toner for electrophotographic printers. The outline, trend and current issues are as follows :
It is thought that color printers will be required higher resolution, less costly, less power consumption and higher print speed. In order to improve resolution, the toner particle size should be smaller from present diameter of 8-9 μm. The fuser unit without oil supply has been examined so far for the cost reduction and the easy maintenance. However, it is difficult to achieve the fusing without oil supply in the approach only on the toner side. On the other hand, we must lower the fusing temperature to reduce power consumption. Therefore, it is necessary to develop a toner which can be melted and fused at a lower temperature. However, the toner of the low temperature melting type shows a tendency to lack durability because the molecular weight of the main resin should be low and then resin strength is poor. This tendency bothers to increase print speed.
