Description of the Related Art Electrophotographic recording in which a toner is adhered to a latent image corresponding to image information formed on a photoreceptor by a developing machine to form a toner image, and the toner image is transferred to a recording sheet. In the method, for example, as shown in JP-A-2-213888 and JP-A-5-142955, an intermediate transfer for once receiving the toner image from the photoconductor and retransferring the received toner image to the recording paper Body-based methods are used in particular for color image printing. In this known example, a single photosensitive member is used, and cyan, magenta, yellow, and black toners are successively superimposed on the intermediate transfer member for each rotation of the intermediate transfer member to form a color image. There is a problem that the time is about four times as long as the black and white printing time. As a method for solving this problem, for example, US Pat. No. 4,935,788 uses four photoconductors for cyan, magenta, yellow and black, and successively forms toner images formed on the respective photoconductors into one drum. A method of forming a color image at the same speed as the black-and-white printing speed by superimposing on an intermediate transfer member is shown. Also, JP-A-7-72
776 shows a method of forming a color image using a belt-shaped intermediate transfer member. Thus, the method using the intermediate transfer member is particularly suitable for printing a full-color image at a high speed. In order to further increase the printing speed by this method, the diameter of the photoreceptor and the developing device are increased, so that the peripheral length of the intermediate transfer member is also increased. In particular, when a toner image on an intermediate transfer member is transferred to a continuous recording sheet, that is, continuous paper, it is necessary to use a seamless intermediate transfer member so that no trace of a joint appears on the image. . However, for example, in the case of a rubber belt, a seamless sheet is formed by extrusion molding into a cylindrical shape, and in the case of a seamless sheet having a long circumference, a large mold is required, and it is difficult to manufacture. There is a problem that it becomes expensive. Another problem is that seams of various lengths cannot be easily manufactured.

る。FIG. 1 shows a first schematic configuration example of a printer which is an electrophotographic apparatus to which the present invention is applied. The four drum-shaped photoconductors 11, 12, 13, and 14 for cyan, magenta, yellow, and black rotate clockwise. For each photoreceptor, the usual electrophotographic process of charging, exposure, and development (for simplicity, charger, exposure device,
The illustration of the developing device and other cleaners is omitted, and only the photoreceptor is shown as a representative). Toner images formed on each photoreceptor are counterclockwise sequentially transferred by the first transfer units 21, 22, 23, and 24. A color image is formed by superimposing on a belt-shaped transfer body 3 as a so-called intermediate transfer body which rotates in a direction. The formed color image is transferred to the recording paper 5 by the second transfer device 4, and the color image on the recording paper 5 is fixed by the fixing device 6.

This makes it possible to prevent the influence of the seam. However, recording paper 5
When the lengths of the recording papers are different from each other, complicated control for synchronizing the running of the recording paper 5 and the belt-shaped transfer body 3 is required so that the seam portion comes to the space between the recording papers each time. On the other hand, when the recording paper 5 is a continuous paper, it is necessary to form an image also at the seam of the belt-shaped transfer body 3, so that the toner image at the seam is disturbed on the recording paper 5. Therefore, a seamless belt-shaped transfer body 3 is required.
