PURPOSE:To avoid the soil within a pressure roller fixing device, by setting a toner collecting means having a magnetized magnetic member and distributing a scraper member and then a cleaning member in the revolving direction of a pressure roll. CONSTITUTION:A magnet 14 is used as a toner collecting means for a cleaning means of a pressure roller fixing device of a copying machine using a single component developer. Then a scraper member 15 and a felt 16 containing the silicone oil are provided in the revolving direction of a pressure roller 11. The mold release characteristics is given to the roller 11 by the felt 16. Thus the toner does not stick easily to the roller 11. A slight amount of the toner, if stuck to the roller 11, is removed by the scraper member 15 and attracted to the magnet 14. The free attachment/detachment is secured for the magnet 14 to facilitate the cleaning and the conversion as well as to simplify the mechanism of the fixing device. |
