Copying machine for both single and multicolor copying

Abstract

Abstract PURPOSE:To enable selective changeover setting of an ordinary transfer system, such as a transfer roll and a transfer corotron in accordance with a single color copying or multicolor copying mode by arranging the transfer corotron and a separation corotron and a conveyance device attachably to or detachably from a photosensitive drum and interlocking the ataching and detaching movement of them with that of a transfer roll. CONSTITUTION:When a single color copying mode is selected, one of yellow, magenta, and cyan color copying buttons on an operation panel is operated to withdraw the transfer roll 9 from the photosensitive drum 3 and to pull up the transfer system of the transfer corotron 10, a separation corotron 11, and the paper conveyance device 12 to the side of the drum 3. A separation plate 28 on a conveyance route is changed over to the side of the single copying mode. Therefore, a transfer paper fed from a paper feeder 27 is conveyed through the conveyance route 29 on the right side of the figure to the drum 3, a toner image developed from a latent image formed on the drum 3 is transferred, and the transferred toner image is fixed with a fixing device 32, and ejected on an ejection tray 30.
