  • Patent number: 6038416
    Abstract: A toner bearing body unit is constituted as one assembled unit including a toner bearing body for holding toners supplied from a toner supply roller of a housing main body at an outer peripheral surface thereof, a toner layer thickness regulating member for electrically charging the toners by applying pressure toward the outer peripheral surface of the toner bearing body and for forming a toner thin layer on the toner bearing body, and a holding member for holding the toner bearing body and the toner layer thickness regulating member. The toner bearing body unit is constituted to be directly attachable to and detachable from an outer side of the housing main body of a developing apparatus. Accordingly, an uniform toner thin layer having a predetermined thickness can be formed stably on the toner bearing body during a long period of use, and the developing apparatus reconstructed so that replacement of the components thereof can be carried out easily.

  • Patent number: 5797075
    Abstract: A developing apparatus includes toner powder in the form of fine colored powder, a toner carrier, and a frictional controlling member for contacting under a pressure with the toner carrier under pressure to frictionally charge the toner powder and form a thin toner layer on the toner carrier. The toner carrier on which the thin toner layer is formed is rotated so as to transport the thin toner layer to an opposing location on a toner image carrier on which an electrostatic latent image is formed to convert the electrostatic latent image into a visible image. The developing apparatus includes a toner supply roller disposed in rotating contact with the toner carrier at a side of the toner carrier, the frictional controlling member being provided at a position in contact with the toner carrier downstream of the toner supply roller; and a rotatable toner scraping member is provided in a neighboring relationship below the toner supply roller and the frictional controlling member.

  • Patent number: 5761568
    Abstract: An electrophotographic imaging apparatus includes a toner image holding body, a transcription unit for transcribing the toner image on the toner image holding body onto a recording medium, and a conveyor for conveying a recording medium toward the toner image holding body and transcription unit. A judging device will judge whether printing is of a first page or not and if it is decided that printing is to be performed on a first page, a first measuring device will measure the electrical characteristic of the toner image holding body prior to the feeding of a recording medium and a transcription voltage will be set depending of this measured result. Thereafter, the recording medium will be conveyed toward the transcription unit where the electrical characteristics of the non-printing region on the recording medium will be measured via a second measuring device and the transcription voltage will be further adjusted.

  • Patent number: 5604572
    Abstract: A developing magnet roller is provided on a developing frame, and a developing agent accommodating cartridge and a toner accommodating cartridge member are fitted detachably into the developing frame. The toner accommodating cartridge member is fitted detachably into the developing agent accommodating cartridge. A developing agent is recovered in the developing agent accommodating cartridge. The developing agent and the developing agent accommodating cartridge are exchanged together from a developing apparatus. The new developing agent accommodated in the exchanged new developing agent accommodating cartridge is circulated by the developing magnet roller. The exchange for the developing agent in the developing apparatus can be realized without the lowering of the developing performance.

  • Patent number: 5602578
    Abstract: An intermediate transcription drum is supported so as to be driven in contacting relationship with a photosensitive belt. The rotating speed of the photosensitive belt driving motor is controlled by a control unit such that one rotation cycle of the intermediate transcription drum becomes a given cycle. An adjustment of the speed control data for the photosensitive belt driving motor is performed in the interval between electrostatic latent image forming. Thereby, a speed difference between the photosensitive belt and the intermediate transcription drum does not occur, and a plurality of the toner images can be transferred and accurately superposed onto the outer surface of the intermediate transcription drum.
