Abstract
An image forming apparatus includes an image carrier which carries an image and a transfer roller including a roller base material which faces the image carrier and rotates. A concave portion is positioned on a peripheral surface of the roller base material. A grip unit on the concave portion grips a recording medium. An elastic layer is disposed on a peripheral surface of the roller base material. The transfer roller passes the recording medium through a nip between the image carrier and the elastic layer which comes into contact with the image carrier via the image carrier and the recording medium to transfer the image carried on the image carrier onto the recording medium. A roller driving unit rotates the roller base material. A control unit controls the roller driving unit and causes the concave portion to face the image carrier to stop the transfer roller.
