摘要： The present invention relates to a color image forming device for forming toner images of a plurality of colors on a medium, and is for improving second transfer efficiency from an intermediate transfer body to the medium. The device has image forming units (12-1 to 12-4) for forming the toner images of the plurality of colors on at least one image bearing body (14-1 to 14-4) by a plurality of developing units (22-1 to 22-4) respectively accommodating toner of different colors; an intermediate transfer body (24); primary transfer means (38-1 to 38-4) for primary transferring the toner images of the plurality of colors onto the intermediate transfer body sequentially for the respective colors; and secondary transfer means (45) for secondary transferring the toner images of the plurality of colors on the intermediate transfer body onto the medium. The image forming units form the toner images of the plurality of colors so that the potentials of toner layers transferred onto the intermediate transfer body (24) are progressively lower in the order in which the plurality of colors are transferred. Since the potential of the toner layer directly adhered to the intermediate transfer body is higher, the directly adhered toner layer becomes easier to be secondary-transferred, and thereby, the secondary transfer efficiency is improved and the reproducibility of the secondary color is improved.
摘要翻译：本发明涉及一种用于在介质上形成多种颜色的调色剂图像的彩色图像形成装置，并且用于提高从中间转印体到介质的第二转印效率。该装置具有用于通过多个显影单元（22-1至14-4）在至少一个图像承载体（14-1至14-4）上形成多种颜色的调色剂图像的图像形成单元（12-1至12-4） 1至22-4）分别容纳不同颜色的调色剂; 中间转印体（24）; 一次转印装置（38-1至38-4），用于将各种颜色的调色剂图像一次转印到中间转印体上，用于各种颜色; 以及用于将中间转印体上的多种颜色的调色剂图像二次转印到介质上的二次转印装置（45）。图像形成单元形成多种颜色的调色剂图像，使得转印到中间转印体（24）上的调色剂层的电位以传递多种颜色的顺序逐渐降低。由于调色剂层直接附着在中间转印体上的电位较高，所以直接附着的调色剂层变得容易二次转印，从而提高二次转印效率，提高二次色的再现性。

摘要： 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 ⅓ or lower than the transfer voltage before a belt position of the initial transfer arrives at a next transfer position.

摘要： 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.

摘要： A charge amount controlling roller serving as a charge amount controlling member is placed to face to a developing roller and is disposed on an upstream side, in a rotation direction of the developing roller, of a developing position at which a photosensitive drum and the developing roller face to each other. The charge amount controlling roller is biased with a voltage having the same polarity as that of non-latent-image portions on the photosensitive drum with respect to the developing roller, thereby reducing extraordinarily charged developing agents, or high charged, low charged, reverse charged toners otherwise causing image defects such as fogs.
