ABSTRACT:
A fixing device has a roller pair; a cover for defining a forward transport path, and a backward transport path for transporting a sheet discharged from the roller pair back to an image former for forming toner images on both sides of the sheet. A sheet detection arm has opposite ends extending respectively in the forward and backward transport paths. A first shaft in the cover is mounted to a center of pivotal movement of the sheet detection arm and extends orthogonal to the sheet transport direction. A secondary shaft transmits rotation of the first shaft when the cover is closed, but not when the cover is opened. A sensor detects whether the sheet is being transported forward or backward based on rotation of the second shaft. The sheet detection arm pivots out of the backward transport path in response to opening of the cover.
