摘要： A semiconductor device has a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type contacted by respective first and second electrodes. A semi-insulating layer extends between the first and second electrodes and there is a first insulating layer between the semi-insulating layer and the first semiconductor region. The sheet resistivity of the semi-insulating layer varies, and this improves the high breakdown voltage of the p-n junction of the semiconductor device between the first and second semiconductor layers, by acting as a shield for charges included on a passivation insulation layer covering the semi-insulating layer and the first and second electrodes. Third semiconductor regions, with corresponding third electrodes, extend around, and are spaced from, the second semiconductor region. The third electrodes extend over the parts of the first semiconductor region adjacent the third semiconductor regions, and this also serve to improve the breakdown voltage. The second electrode may also extend over the part of the first semiconductor region adjacent the second semiconductor region to cover the p-n junction therebetween.

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 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： A transfer device is provided including an intermediate transfer belt and transfer rollers associated with respective of photosensitive drums. Each of the transfer rollers and the intermediate transfer belt define therebetween a contact range of which center lies downstream of the center of a contact range (transfer nip region) defined between the associated photosensitive drum and the endless belt in the direction of movement of the endless belt. The transfer roller deforms the path of movement of the intermediate transfer belt by contacting the intermediate transfer belt, and the resulting deformation causes the intermediate transfer belt to contact the periphery of the photosensitive drum over a predetermined range.

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.
