Abstract
A fixing apparatus for fusing and fixing an unfixed developer by heating/pressurizing a recording medium on which an image of the unfixed developer is formed, includes a fixing roller cleaning unit for cleaning surfaces of fixing rollers, and a propinquity/separation mechanism for moving the fixing roller cleaning unit close to and away from the fixing roller. The fixing apparatus operates the propinquity/separation mechanism so as to make the fixing roller cleaning unit contact the fixing roller when a temperature of the fixing roller becomes equal to or higher than a softening temperature of a developer. The fixing apparatus operates the propinquity/separation mechanism so as to move the fixing roller cleaning unit away from the fixing roller when a temperature of the fixing roller becomes lower than the softening temperature of the developer.
