In an image forming apparatus, a sheet that has been transported in a certain direction is selectively transported to one of first and second transport routes by a route changer mechanism. A first cover and a second cover are openably provided on a main body of the apparatus to respectively allow the first and second transport routes to be accessible to outside of the apparatus main body when set in an opened state. An operative mechanism is provided to open the first cover in association with opening of the second cover.
