    摘要： A Transfer device (10) includes an intermediate transfer belt (41), a plurality of intermediate transfer roller (34A-34D) and a transfer member moving mechanism (20). The transfer member moving mechanism moves the intermediate transfer rollers (34A-34D) between pressing positions causing the intermediate transfer belt (41) to be pressed against respective photoreceptor drums (31A-31D) and separate positions causing the intermediate transfer belt (41) to be separate from the respective photoreceptor drums (31A-31D). The transfer member moving mechanism (20) causes a second pressing position of the intermediate transfer roller for monochrome (34A) in monochromatic image forming to be different from a first pressing position of the intermediate transfer roller for monochrome (34A) in full-color image forming so that an amount of pressing of the intermediate transfer belt (41) by the intermediate transfer roller for monochrome (34A) becomes greater in monochromatic image forming than in full-color image forming.

    摘要： An image forming apparatus includes a transfer belt unit which has an intermediate transfer belt for supporting toner images and primary transfer rollers for pressing the intermediate transfer belt against corresponding photoreceptor drums and moves the intermediate transfer belt along the surface of each photoreceptor drum to transfer the toner images to the intermediate transfer belt. The intermediate transfer belt is formed so as to be 30 μm to 50 μm in average thickness, each primary transfer roller is arranged at a position, along the moving direction of the intermediate transfer belt, which is deviated downstream with respect to the moving direction from the position where the intermediate transfer belt is in contact with the photoreceptor and which is projected toward the photoreceptor drum side so as to press the intermediate transfer belt against photoreceptor with a nip pressure ranging from 10 gf/cm2 to 40 gf/cm2.

    摘要： An electrostatic charger according to the present invention includes a needle electrode, a support, and a cleaning member. The needle electrode has a linear array of needles. The support can move along the linear array. The cleaning member is supported by the support rotatably on an axis perpendicular to the linear array. While the support is moving with the cleaning member along the linear array, the cleaning member rotates, with the needles sinking in order into and subsequently coming in order out of the cleaning member. When the cleaning member makes each rotation while moving with the support, some of the needles sink in positions into the cleaning member where any other needles did not sink when the cleaning member made the previous rotation.

    摘要： A waste toner collecting container which is used in a color image forming apparatus and can be removed from the machine and stores waste toner particles which have not been transferred to recording paper and have been collected, is constructed such that an air sealing member is disposed at the coupling between the waste toner collecting container and a conveying member for conveying the collected waste toner into the waste toner collecting container to prevent the waste toner from seeping out at the coupling when the waste toner is conveyed and to seal the collecting port so that no waste toner will spill out from the waste toner collecting container which has been removed for replacement after the waste toner collected and conveyed therein has reached the predetermined amount.

    摘要： In an image forming apparatus a primary transfer is carried out such that toner images on a plurality of photoreceptors are transferred and laminated onto an intermediate transfer member, and a recording paper and the intermediate transfer member are sandwiched between a secondary transfer roller disposed so as to be in contact with the intermediate transfer member and a secondary transfer counter roller disposed opposite to the secondary transfer roller, to carry out a secondary transfer that the toner images on the intermediate transfer member are transferred onto the recording paper. At the time, an electric field is applied to the recording paper, and further the secondary transfer counter roller is switched by a switch between grounded state and floating state so that a potential difference between the intermediate transfer member and the secondary transfer roller can be adjusted.
