Abstract
An image forming apparatus of the present invention includes an image carrier on which a toner image is to be formed, and a sheet support member for conveying a sheet, carrying the toner image thereon, in cooperation with the image carrier. The image carrier and sheet support member are driven such that their surfaces move in the same direction, as seen at a contact position where the two surfaces face each other via the sheet. An electric field, forcing the toner image toward the image carrier, and an electric field, forcing it toward the sheet, are formed between the surface of the image carrier and that of the sheet at positions upstream and downstream, respectively, of the contact position in the direction of movement of the sheet.
