摘要： 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.

摘要： An image forming apparatus includes an image carrier which moves while carrying 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 grips a recording medium by the grip unit when the concave portion faces the image carrier and passes the recording medium through a nip between the image carrier and the elastic layer when facing each other so that the image carried on the image carrier is transferred on the recording medium. A roller driving unit rotates the roller base material. A control unit controls the roller driving unit to adjust a timing for forming the nip.
