  • Color image forming apparatus
    Patent number: 6522861
    Abstract: A color image forming apparatus is provided wherein toner images formed on a plurality of image carriers are primarily transferred onto an intermediate transfer object, and then, are secondarily transferred onto a recording sheet. The color image-forming apparatus includes an intermediate transfer member, a longitudinal direction of which is arranged in substantially a vertical direction, and onto which toner images formed on image carriers are sequentially transferred in such a manner that the toner images overlap relative to each other so as to form a color toner image on the intermediate transfer member. In addition, a transferring device is provided to transfer the color toner image formed on the intermediate transfer member onto a transfer sheet. The intermediate transfer member and the image carriers are integrated into a rack, and the rack is drawable in substantially a horizontal direction with respect to a mainframe of the color image-forming apparatus.
