PURPOSE:To keep always a fixing roller clean, by forming the fixing roller, with which a powder image is brought into contact, with materials to which a toner is difficult to stick and forming a cleaning roller, which is brought into press- contact with this fixing roller, with materials to which the toner is easy to stick. CONSTITUTION:A fixing roller 31 and a press-contact roller 32 are rotated in directions of arrows respectively, and heates 33 and 34 are provided in rollers 31 and 32. Rollers 31 and 32 have elasticity of silicone rubber rollers or the like and consist of materials which are difficult to offset, and hard cleaning rollers 35 and 36 consisting of materials such as aluminum which are easy to offset are brought into press-contact with the circumferential faces of tollers 31 and 32. Even if a recording paper 6 passes between rollers 31 and 32 and the toner is stuck to rollers 31 and 32, rollers 31 and 32 are always kept clean to prevent the dirt and the damage of the recording paper because the toner is transferred to cleaning rollers 35 and 36. |
