PROBLEM TO BE SOLVED: To provide an image forming apparatus in which the deterioration of an image quality due to transfer scattering and defective transfer caused at the time of transferring a toner image from an image carrier to the various kinds of transfer materials such as paper is suppressed. SOLUTION: In the image forming apparatus by which the toner image is formed on the image carrier and is transferred to the transfer material held and fed by the image carrier and a transfer material carrier and the image carrier and the transfer material carrier are driven so as to make both surfaces move in the same direction at a contact part where they come into contact by holding the transfer material, an electric field in a direction where the toner image is moved to the side of the image carrier 11 is formed between the surface of the image carrier 11 and the surface of the transfer material 15 on an upstream side in the moving direction of the transfer material from the contact part, and an electric field in a direction where the toner image is moved to the side of the transfer material 15 is formed between the surface of the image carrier and the surface of the transfer material on a downstream side from the contact part.
