PURPOSE:To prevent the dirt of the rear face of a material to be fixed and prevent this material from being wound onto rotary materials by providing cleaning members for heating and press-fixing rotary materials to sweep sufficiently the dirt off the surface of rotary materials. CONSTITUTION:A copy paper to which a toner on a photosensitive drum is transferred is separated from the drum and is carried by a carrying belt 2 and is inserted between a heating roll 3 and a press-fixing roll 4 in a fixing part 1. A cleaning roll 23 where a polyimide felt is stuck onto a silicone rubber is pressed to the heating roll 3, and the toner transferred onto the heating roll 3 is swept. The second cleaning roll 24 having the same structure is pressed to the press-fixing roller 4. Pressing between the press-fixing roll 4 and the cleaning roll 24 is released by the operation of the second roll press-fixing lever 12. |
