子写真装置。 The toner image formed on the photoreceptor is transferred onto a transfer sheet, the transferred sheet is sent to a fixing section including a pair of rotating fixing rollers, and after the toner image is fixed on the sheet, it is discharged. In such an electrophotographic apparatus, the fuser main body, which pivotally supports the pair of fixing rollers, is fixed on the apparatus main body at the downstream end in the sheet conveyance direction, and the fuser main body is fixed on the apparatus main body at the upstream end. The fuser main body is supported so as to be movable up and down, and the fixing device body is moved in response to an increase in the rotational load of the fixing roller that occurs when the sheet is caught between the pair of fixing rollers. An electrophotographic device characterized in that it is swingable in the sheet advancing direction using an end portion as a fulcrum.
