摘要： An image forming apparatus having deflection scanning type and line type exposing devices and first and second developing devices arranged around a photoconductive element, so that parts around the photoconductive element are arranged with ease to promote the miniaturization of the apparatus. The exposing devices are selected based on the principle that the image quality is enhanced for an image of particular color and is lowered for an image of another color expected to be printed less frequently. Specifically, the deflection scanning type exposing device forms the image of the particular color, and the line type exposing device which has an inherently long optical path and simple structure forms the image of another color. Fans are provided to produce cooling air flow to the line type exposing device and to draw out toner dirt and ozone produced by the charger associated therewith. The line type exposing device and the associated charger are electrically insulated from each other and mounted in a common casing. Cleaning elements are provided to clean the charger and the line type exposing device during withdrawal of these elements from the photoconductive element.

摘要： A multi-beam detecting apparatus adapted to an optical system in which a recording medium is scanned by a plurality of light beams emitted from respective light sources, includes a photodetector, a light interrupting member, and a control circuit. The photodetector produces detection signals when the corresponding light beams come to a predetermined position. The light interrupting member is interposed between the light sources and the light detecting member, and has transparent portions related to the respective light beams. A controlling circuit controls ON/OFF states of the light source in accordance with the respective detection signals related to the corresponding light beams passing through the respective transparent portions in the light interrupting member.

摘要： An electrophotographic copier, facsimile machine, laser printer or similar image forming apparatus for reproducing an image on a paper sheet by transforming an image signal representative of the image into an image forming signal by pulse width modulation, causing a spot beam in the form of a laser beam which is modulated by the image forming signal to scan a photoconductive element to form an electrostatic latent image thereon, developing the latent image to render it visible, and transferring the visible image to a paper sheet. The laser beam output, the set pulse widths of the image forming signal (beam turn-on times) and the bias voltage for development are changed in association with the deterioration of the laser beam power and the sensitivity of the photoconductive element.

摘要： A bicolor image forming apparatus having first and second exposing means and first and second developing means arranged around a photoconductive element. The first and second developing means are implemented as a deflection scanning type and a line type, respectively. Parts around a photoconductive element are arranged with ease to promote the miniaturization of the apparatus. This stems from the principle that the image quality may be enhanced for an image of particular color and lowered for an image of another color expected to be printed less frequently. Specifically, the apparatus has deflection scanning type exposing means for forming the image of particular color, and line type exposing means which has an inherently long optical path and simple structure for forming the image of another color.

摘要： Servicing of an image forming device, such as a digital photocopier, is made convenient by providing an access opening exposing each of a number of prescribed serviceable components enclosed in a sealed casing. These serviceable components may include a light source scanner, lens group and beam detector. The casing bears removable cover units on the access openings. The serviceable components are located under the access openings, fixed in place by the cover units or elements attached to the cover units. Electrical switches coupled to the cover units may deactivate the components when the cover units are removed.

摘要： In an image forming apparatus, a device for removing an image forming substance from a paper or similar image holding medium senses the orientation of fibers constituting the paper. While a light beam is emitted obliquely toward the paper, the diffused distribution distribution of the resulting reflection is measured in order to determine the orientation of the fibers. A preselected relation is set up between the fibers and the direction of paper transport on the basis of the determined orientation. Further, a condition for applying an unstabilizing liquid to the paper and a condition for drying the paper are varied on the basis of the determined orientation.
