Abstract
An image forming apparatus includes a developing roller including a magnet in which a plurality of magnetic poles are arranged and a rotatable sleeve which conveys a developing agent including toner and carrier to develop a latent image formed on a photoconductor, a motor configured to rotate the sleeve and a rotational direction of a motor control section configured to rotate the motor forward or reversely when an image forming job is completed, to rotate the sleeve in a direction reverse to a rotational direction of the sleeve in the image forming job for a reverse rotation time and then rotate the sleeve in a direction the same as the rotational direction of the sleeve in the image forming job for a forward rotation time shorter than the reverse rotation time.
