Abstract
An image forming apparatus includes: a transfer unit T2 including the inside transfer roll 29, the outside transfer roll 30 transfers the toner image from the toner image holding belt B onto the recording sheet that passes through the transfer region Q4 when transfer voltage is applied to between the inside transfer roll 29 and the outside transfer roll 30; electric-field adjusting conductive member 51 disposed in proximity to and along the inner side of the toner image holding belt B leaving the transfer region Q4 at a position located downstream of the transfer region Q4; and electric-field adjust-potential applying means 53; 54 applies a potential, which weakens an electric field developed between the outside transfer roll 30 and the inside transfer roll 29 in a region located downstream of the transfer region Q4, to the electric-field adjusting conductive member 51.
