摘要： An image fixing apparatus having a linear heating body, an endless belt entrained around thereon, means for supplying electricity to the linear heating body with pulse electricity, a pressure body which interposes a subject to be fixed having an image with the endless belt, the image is heated by the linear heating body by way of the endless belt, and thereafter being cooled and removed from the endless belt is provided. The image is formed by a toner containing a binder which contains a resin as a main component, and either a softening point or a melting point of the toner is 50 to 160 °C, and a viscosity of the toner is 10 to 10 13 centipoise at softening point or a melting point or more of the toner.

摘要： An image forming apparatus of the present invention includes a first and a second intermediate image transfer belt contacting each other to form a nip for secondary image transfer. While the nip is heated, a sheet is passed through the nip to thereby transfer toner images respectively formed on the first and second belts to opposite surfaces of the sheet at the same time. The nip is sized such that image transfer and fixation can be effected at temperature higher than the melting point or the softening point of toner by 5°C to 50°C.
摘要翻译：本发明的图像形成装置包括第一和第二中间图像转印带，其彼此接触以形成用于二次图像转印的辊隙。当辊隙被加热时，片材通过辊隙，从而将分别形成在第一和第二带上的调色剂图像同时转印到片材的相对表面。压区的尺寸使得图像转印和固定可以在高于调色剂的熔点或软化点的温度下进行5℃至50℃。
