Abstract:
An image forming apparatus includes a photosensitive drum, a charging roller, a transfer roller, a first bias application unit, a second bias application unit, and a control unit. The charging roller contains an ion conductive material. The first bias application unit applies a first bias to the charging roller. The second bias application unit applies a predetermined bias to the transfer roller. The control unit controls the first bias application unit not to apply the first bias to the charging roller in a non-image forming period in which a toner image is not formed on the photosensitive drum. The control unit controls the second bias application unit to apply the second bias, which is a bias that can electrically charge the surface of the photosensitive drum, to the transfer roller in the non-image forming period.
