For guiding printing paper, the guide roller is provided with a contact surface that comes into contact with a surface of the printing paper on which an unfixed toner image is produced.

The contact surface of the guide roller is provided with a blade contact portion, such as a projection or groove, for causing the cleaning blade to vibrate.
