    摘要: A color image forming apparatus includes a carrier belt which runs along a transport path of a recording medium to transport the recording medium. A number of image-forming sections are aligned in the transport path. Each of the plurality of image-forming sections forms a toner image of a corresponding color included in an image signal. A plurality of transfer units are provided, with each being disposed to oppose a corresponding one of the number of image-forming sections. Each of the number of transfer units transferring the toner image of the corresponding color to the recording medium. A fixing unit is provided that fixes the toner image to the recording medium. A controller is provided that detects a number of colors in the image signal. The controller sets one set of speeds from a plurality of different sets of speeds in accordance with the number of colors. Each set of speeds includes a speed of the carrier belt, a speed at which each of the image-forming sections forms a respective toner image of a corresponding color, and a speed of the fixing unit. The speed of the carrier belt, the speed at which each of the image-forming sections forms a respective toner image of a corresponding color, and the speed of the fixing unit of any one respective set of speeds are substantially equal to each other.

    摘要: A developer cartridge is used with an image forming apparatus. The developer cartridge has a groove which formed in a longitudinal end surface of thereof and extends in an insertion direction of the cylinder. A strip-shaped projection formed in the image forming apparatus projects extends in the insertion direction. When the developer cartridge is fully inserted into the image forming apparatus, the groove receives the projection so that the projection is at a predetermined position relative to the developer cartridge. Two first walls define the groove which is progressively wide as the circumference is approached. A second wall rises from the longitudinal end surface of the developer cartridge and is continuous with one of the two first opposed walls. The second wall smoothly guides the projection into the groove.

    摘要: A color image forming apparatus provides the prolonged life of the photosensitive drums, carrier belt, and toner of the respective colors and improves the quality of the printed color image. A carrier belt transports a recording medium placed thereon so that the recording medium passes through a plurality of printing mechanisms which print images of different colors on the recording medium in superposition. Each printing mechanism prints an image of a corresponding color. The printing mechanism is adapted to be moved into its operative position where the photosensitive drum of the printing mechanism is in contact with the carrier belt to print the image on the recording medium, and into its non-operative position where the photosensitive drum of the printing mechanism is not in contact with the carrier belt. A controller receives print data from a host device such as a personal computer and checks each page of the print data to determine whether any one of a predetermined plurality of colors is missing in the page. If a particular color is missing in the print data, then the controller outputs an UP signal to a positioning mechanism for a corresponding printing mechanism. If the color is not missing, then the controller outputs a DOWN signal. The printing mechanism moves a corresponding printing mechanism into the operative position if the UP signal is received from the controller and into its operative position if the DOWN signal is received.

    摘要: A sheet hold flap 18 is arranged on an upper side of a vicinity of a rear end portion of a sheet table 7 to which a sheet is continuously supplied from a copier or the like. The sheet hold flap is switched to an upper initial position and a sheet holding position by a solenoid 17. There is carried out a control of holding a rear end portion of a sheet P by driving the sheet hold flap to the sheet holding position after taking in a sheet to the sheet table and returning the sheet hold flap to the initial position to escape from a sheet path in taking in a successive sheet. Sheet jamming by floating up the sheet is prevented by holding a sheet on the sheet table until immediately before taking in the successive sheet.

    摘要: A clincher 17 of an electric stapler is provided with a press blade 19 for moving up and down to and from a driver. Recess grooves 21 are formed at two contiguous portions of a stapler injecting port of a driver unit 12 and a front end of the press blade is received by the recess grooves. After pinching sheet by the driver unit and the clincher to bind by a staple, the press blade presses the sheet to the recess groove to press a fold line. An excellent finish is achieved at a binding processing apparatus constituted by the electric stapler and a sheet folding mechanism.
