ABSTRACT:
An image forming apparatus includes an image bearing member to form a toner image thereupon. A transfer device is positioned adjacent to the image bearing member to transfer the toner image formed on a surface of the image bearing member onto a surface of a recording medium. A cleaning device cleans the surface of the image bearing member by removing remaining toner on the surface of the image bearing member after the toner image has been transferred onto the recording medium. A fixing device is provided in an upper part of the image forming apparatus to fix the toner image transferred onto the surface of the recording medium when the recording medium passes through the fixing device. An open/close member is rotatably supported by a main body of the image forming apparatus and opens and closes a recording medium conveying path between the transfer device and the fixing device. And, a shutter is movably supported to move between a protecting position to cover a part of the surface of the image bearing member facing the outside of the image forming apparatus when the open/close member is opened and a retreating position to open the part of the surface of the image bearing member when the open/close member is closed. The retreating position of the shutter is set in a space between the image bearing member and the fixing device and the shutter is movably supported by the main body of the image forming apparatus such that the shutter moves with a first face of the shutter continuously facing the image bearing member when the shutter moves between the protecting position and the retreating position.
