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.

Description

technical field [0001] The present invention relates to a fixing device suitably used in an electrophotographic image forming device and an image forming device including the fixing device. Background technique [0002] In image formation using electrophotography, a photoreceptor with the same potential is exposed to light corresponding to image information to form an electrostatic latent image, and the formed electrostatic latent image is developed with a developer to make it developable. The image that can be developed is transferred to recording paper or the like, and the developer on the transferred recording paper is fixed by a fixing device to form a firm recorded image. [0003] A fixing device used for such image formation is generally composed of a heating roller and a pressure roller, and is configured such that the recording paper transferred with a developable developer is passed by pressing the pressure roller against the heating roller. ...
