    摘要： A uniform image is obtained by matching the sliding friction force, the moving speed and the developing agent in a developing region of two developing rollers and an electric characteristic of a photosensitive body used for image development. Two developing rollers rotating in directions opposite to each other are used, the moving direction of the first developing roller being opposite to the moving direction of the photosensitive body, and a circumferential speed ratio of a circumferential speed of the first developing roller to a circumferential speed of the photosensitive body is within a rage of 0.5 to 2.5; and the moving direction of the second developing roller is equal to the moving direction of the photosensitive body, and a circumferential speed ratio of a circumferential speed of the second developing roller to a circumferential speed of the photosensitive body is within a range of 1.5 to 3.5. A ratio of the sliding friction force between a magnetic brush for developing agent and the photosensitive body formed in the first developing roller and the sliding friction force between a magnetic brush for developing agent and the photosensitive body formed in the second developing roller is within a range of 0.9 to 2.1.

    摘要： An image forming apparatus includes: a first image forming unit having a first printing section for forming a first image on the paper; a second image forming unit having a second printing section for forming a second image on the paper; and a paper conveying unit for conveying the paper from the first image forming unit to the second image forming unit. Accordingly, two kinds of image can be formed employing one image forming apparatus. The first image and the second image may be formed using the same recording material (toner) or different recording materials (toners).

    摘要： A toner cartridge includes a container for containing toner of a volume of 2500 cm3 or more. The container defines an opening portion, a cap is fixed to the opening portion of the container, and the cap defines a first semicircle opening portion. A film covers and seals the first semicircle opening portion of the cap. A shutter is rotatably disposed on the cap and the shutter defines a second semicircle opening portion capable of corresponding to the first semicircle opening portion of the cap, the shutter having a diameter of 70 mm or above.

    摘要： An image forming apparatus includes a developing unit having a photoreceptor, for making an electrostatic latent image on a surface of the photoreceptor visible as a toner image. A toner hopper stores toner to be supplied to the developing unit and a cleaning device removes and recovers the toner remaining on the surface of the photoreceptor after the toner image has been transferred onto a recording material. A toner transporting passage is connected between the cleaning device and the toner hopper, through which the toner recovered by the cleaning device is returned to the toner hopper. A toner exhausting port is disposed at a part of the toner transporting passage, from which the toner being returned from the cleaning device side is exhausted outside the toner transporting passage. An opening and closing member selectively opens or closes the toner exhausting port, wherein an inner diameter of the toner exhausting port is made larger than that of the toner transporting passage.

    摘要： A fixing device has a web unit with a housing having two shaft members in parallel with each other, the housing defining a through hole on each of two lateral sides of the housing. The web unit also has a web member windably supported by the two shaft members, and a handle having two protrusion protruded from a lateral surface of the housing to outside of the housing. Each of the two protrusions defines a first width and a second width larger than the first width. The fixing device also has a fixing device frame to be detachably disposed to the web unit. The fixing device frame has a guiding groove with a groove through which the two protrusions are guided on the basis of the first width, and a guiding portion at an end of the groove to allow the two protrusions to be changed from the first width to the second width. The attachment or detachment of the web unit to or from the fixing device frame is regulated corresponding to a position of the handle with respect to the housing.
