Abstract
An image forming apparatus includes: an image forming unit which forms a toner image on an image carrier; a conveying unit which conveys a recording medium; a transfer unit which transfers the toner image formed on the image carrier to the recording medium conveyed by the conveying unit in a transfer nip; a pre-transfer charging unit which imparts an electrical charge, having a polarity opposite to a normal charge polarity of a toner, to the recording medium conveyed by the conveying unit on an upstream side of the transfer nip in a conveyance direction; and a destaticizing unit which removes a part of the electrical charge that is imparted to a surface of the recording medium by the pre-transfer charging unit and corresponds to unevenness on the surface of the recording medium on an upstream side of the transfer nip in the conveyance direction.
