ラー複写機。Four developing devices each having yellow, magenta, cyan, and black toner are placed downstream of the exposure position along the periphery of the photoconductor drum, and at the downstream transfer position, the developer contacts the photoconductor drum and is exposed to light at this contact portion. A transfer drum is provided with a clamper that rotates in the same direction at the same circumferential speed as the body drum, clamps the leading edge of the transfer paper, and wraps the transfer paper without shifting it. The latent images formed by exposing the photosensitive drum to each rotation are developed with different color toners, and the leading end is clamped to the transfer drum and transferred onto the wrapped transfer paper in a superimposed manner. In a color copying machine, when making monochrome copies, the photoreceptor is exposed once without color separation of the original, the latent image formed is developed with toner of any one color, and then transferred to transfer paper wrapped around a transfer drum. During monochrome copying, compared to full-color copying, the paper feed timing and document exposure timing are adjusted based on the rotation timing of the photosensitive drum, so that the leading edge of the transfer paper is transported by at least the length in the transport direction that is clamped by the clamper. A color copying machine characterized in that the color copying machine is controlled to delay the time longer than the time required for copying.
