Abstract
An image forming apparatus has a photoreceptor drum and a toner image receptor for forming toner images on both sides of a transfer sheet. The apparatus includes a photoreceptor drum; a toner image forming unit for forming a toner image on the photoreceptor drum; a toner image receptor, disposed facing the photoreceptor drum, for holding the toner image; a first transfer unit for transferring the toner image, on the photoreceptor drum, to one side surface of a transfer sheet; a second transfer unit for transferring the toner image, on the toner image receptor, to the other side surface of the transfer sheet; a fixing unit for fixing the toner image transferred to both side surfaces of the transfer sheet; an image size discriminator for discriminating a size of an image to be formed by the image forming apparatus, and for generating a signal corresponding to the discriminated size; and a control unit for controlling the image forming apparatus so that either the toner image corresponding to one page is formed on the toner image receptor or the toner image corresponding to plural pages is formed on the toner image receptor according to the signal generated by the image size discriminator.
