装置の定着器。[Claims for Utility Model Registration] A device comprising a pressure roller and a fixing roller that presses the pressure roller, and transmits rotation from a drive system to a fixing gear coaxial with the fixing roller through a drive gear train that meshes with the fixing gear. In the fixing device of an electrophotographic apparatus, which rotates both rollers and fixes the transferred image by passing a sheet of paper between the rollers after the image has been transferred, the fixing device is provided in the apparatus main body so as to be movable in a direction in which the drive gear train and the fixing gear are disengaged. A fixing device for an electrophotographic device.
