The present invention provides a display element, which is driven at a low voltage, displays a high-contrast image with few density irregularities, and has improved image holding property. The method includes reading an image of a conveyed document, detecting a sheet type of the conveyed document, and controlling, in a case where the detected sheet type is the predetermined sheet type, an image to be printed on the conveyed document, and controlling, in a case where the detected sheet type is not a predetermined sheet type, an image not to be printed on the conveyed document. 00 mole percent mercapto groups and from about 0. The pixel blocks can be made in various equilateral polygonal cross-sectional shapes of designated length, typically embodied in an equilateral cube shape. Thus, the primary winding includes first and second primary windings disposed on the first and second legs and the secondary winding includes first and second secondary windings disposed on the first and second legs. An embodiment comprises transmitting control information after the beginning portion is transmitted and before the completion portion of the payload portion is transmitted.
