Our company has developed a type of belt which consists of thin nickel base material for the color fixing process. By using this system, the time of waming up can be completed in a short period. The life of this fixing unit is limited by the cracking of the belt, probably caused by the fatigue of metal. In order to improve the material, it was considered important that the voltage/current relationship be least affected by frequency variation. After conducting a parameter design, a new material was developed before product development spending only a half year. As a result, the belt life caused by cracking was extended three times compared with the current material.
