摘要： A constant-voltage diode has a first semiconductor region of a first conductivity type, an adjoining semiconductor region of a second conductivity type, a third semiconductor region of the second conductivity type adjoining the second semiconductor region, and a fourth semiconductor region of the first conductivity type partially surrounded by the second semiconductor region. At low reverse biases between a cathode electrode and an anode electrode, the behavior of the device is determined by the pn junction between the first and second semiconductor regions. As the reverse biasing increases, the depletion layers of that junction will reach the fourth semiconductor region, but the reverse bias at this time is insufficient to break down that junction. A further increase of reverse bias causes breakdown of the pn junction between the third and fourth semiconductor regions. This effect is achieved by suitable impurity concentrations in the semiconductor regions. A plurality of fourth semiconductor regions may be provided, and a bi-directional structure can be obtained by providing a polarity reversed structure with the first semiconductor region in common.

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 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.
