Abstract
An image forming apparatus includes: a latent image carrier 1 to form a latent image in accordance with an image signal; a developing unit 14 to develop the latent image with a predetermined toner; an intermediate transfer body 2 coming into contact with the latent image carrier 1 so that the intermediate transfer body can be rotated together with the latent image carrier, the intermediate transfer body being capable of transferring a toner image formed on the latent image carrier 1; a transfer roller 4 to simultaneously transfer the toner image held on the intermediate transfer body 2 onto a recording medium 11; and a transfer roller 3 arranged in the downstream close to a contact region (nip portion) of the latent image carrier 1 with the intermediate transfer body 2, the transfer roller 3 being arranged on a side of the intermediate transfer body 2 reverse to a toner image holding surface so as to transfer the toner image on the intermediate transfer body 2 by forming a transfer electric field between the latent image carrier 1 and the intermediate transfer body 2 when a voltage, the polarity of which is opposite to the electrical charging polarity of the toner image, is impressed.
