Abstract
An image forming apparatus having an image carrier that carries a toner image; an opposed member that is provided so as to be opposed to the image carrier; an application device that applies a bias to the opposed member; and a control device that controls the application device to apply a first bias and thereafter a second bias to the opposed member so as to remove toner from the opposed member. The first bias has an absolute value that is large enough to cause discharge from the opposed member into air. The second bias has an absolute value that is too small to cause discharge from the opposed member into the air, and has a reverse polarity to the first bias.
