  • Patent number: 6922542
    Abstract: An image forming apparatus in which respective color visible images on tandem-arrayed plural photoconductor drums are sequentially overlay-transferred onto an intermediate transfer belt by application of a primary transfer voltage by intermediate transfer rollers, then the images are transferred at a time from the belt onto a print sheet by application of a secondary transfer voltage by a paper transfer roller. The same primary transfer voltage is applied to the respective color intermediate transfer rollers from one power source. In the intermediate transfer belt, a relative dielectric constant, a surface resistance and a volume resistance are controlled such that potential charged by initial transfer is attenuated to ? or lower than the transfer voltage before a belt position of the initial transfer arrives at a next transfer position.

  • Patent number: 6850726
    Abstract: An image forming apparatus or method which uses plural image forming units to form visible images of different colors by making developers of different colors adhere to image holders such as photosensitive drums electrostatically. In this apparatus or method, intermediate transfer electrode members such as intermediate transfer rollers are opposite to the image holders of the image forming units with a belt transfer member between them and voltage is applied to transfer images electrostatically from the image forming units to the belt transfer member in sequence in a way that the transferred images on the belt overlap each other. Each of the intermediate transfer electrode members is located on the belt surface away from a point (transfer nip) at which a corresponding image holder contacts the belt.

  • Patent number: 5211490
    Abstract: An inked ribbon cassette comprising an ink supply felt, a first gear arranged in contact with the felt and a second gear in engagement with the first gear. An ink ribbon is pinched between the first and the second gears and driven by the first and the second gears upon rotation thereof. Accordingly, ink is transferred from the felt to the first gear, and in turn, from the first gear to the ink ribbon. There are grooves in the first gear for containing ink therein ink is excessively transferred from the ink supply felt to the first gear. The grooves are preferably provided in bottom lands of the first gear by increasing the whole depth of the first gear.
