摘要： A developing device configured to form toner cloud without making toner particles adhere to the electrostatic transport substrate having electrodes. By applying periodical voltages to electrodes, electrically charged toner particles float on the electrostatic transport substrate. Also, a rotatable toner transporter designed to carry toner particles floating on the electrostatic transport substrate. Also, a two-component developer bearer including a sleeve with magnets on which the two-component developer is borne. The two-component developer borne on the sleeve is sent to the toner transporter by rotation of the sleeve. There, toner particles are transported to the toner transporter because of the electric bias applied between the two-component developer bearer and the toner transporter. Toner particles electrically floating on the toner transporter are sent to the photoconductor for development.

摘要： A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.

摘要： A tandem image forming device for an image forming apparatus of the present invention includes a plurality of image forming means arranged side by side along an intermediate image transfer belt. The image forming means each include a developing device and a cleaning device arranged around an image carrier. One of nearby image forming means has its cleaning device positioned above the developing device of the other image forming means, e.g., an agitating section forming part of the image forming means. This configuration insures smooth circulation of a developer and therefore obviates an irregular developer distribution while reducing the overall size of the image forming device.
