| Zusammenfassung: | A fusing device for an electrophotographic image forming apparatus includes a fusing roller which includes a tubular heat pipe, both ends of which are sealed and in which a predetermined amount of a working fluid is contained, a cylindrical roller which surrounds the heat pipe, and a heater which is installed between the cylindrical roller and the heat pipe, and a pressing roller which presses a sheet of paper passing between the pressing roller and the fusing roller. A rubber layer having a predetermined thickness is formed on a surface of the cylindrical roller so as to form a fusing nip with the paper. |
