<p>An image forming apparatus (1) includes a controller (160, 132) that controls rotational driving of a magnetic roller (21) and rotational driving of a developing roller (20). The controller (160, 132) is capable of performing a toner collecting mode when no image formation is performed. In the toner collecting mode, the magnetic roller (21) and the developing roller (20) are intermittently rotated in a direction reverse to a direction in which the magnetic roller 21 and the developing roller (20) are rotated during image formation, then the magnetic roller (21) is made to rotate in a forward direction, and then, the magnetic roller (21) is rotated in a backward direction.</p> |
