  • Publication number: 20050238922
    Abstract: A multilayer-reflection-film-coated substrate includes a substrate, a multilayer reflection film formed on the substrate and reflecting an exposure light, and a conductive film formed on an opposite side of the substrate from the multilayer reflection film in a region excluding at least a peripheral portion of the substrate. The conductive film is made of a material containing chromium (Cr). The conductive film contains nitrogen (N) on a substrate side and at least one of oxygen (O) and carbon (C) on a surface side. A reflection type mask blank for exposure is obtained by forming an absorber film for absorbing the exposure light on the multilayer reflection film of the multilayer-reflection-film-coated substrate. A reflection type mask is obtained by forming a pattern on the absorber film of the reflection type mask blank for exposure.

  • Patent number: 5619308
    Abstract: In an electrophotographic image forming apparatus including a photoconductive drum, the photoconductive drum is electrically charged by a corona charger, and light corresponding to an image is projected onto the photoconductive drum by an exposure optical system, thereby forming an electrostatic latent image thereon. Thereafter, the formed electrostatic latent image is developed with toner by a developing unit to form a toner image thereon, and then the toner image is transferred onto a sheet of paper. There is further provided a voltage sensor for detecting a surface voltage at at least one position of the photoconductive drum. An operation value of at least one of the corona charger, the exposure optical system and the developing unit is adjusted by an adjustment controller based on the surface voltage detected by the voltage sensor at a timing between respective image forming processes when an image forming process is continuously repeated a plurality of times.

  • Patent number: 5499079
    Abstract: An image density control apparatus for controlling an image density on a photoconductor surface has a charger for charging the photoconductor surface uniformly. A laser beam is scanned over the photoconductor surface to form a standard latent image having an electric potential distribution on the photoconductor surface. A potential detector detects an electric potential distribution of the standard latent image, and a developer develops a standard toner image from the standard latent image. A density detector detects a density of the standard toner image. Based on the detected electric potential distribution and the detected density, an appropriate gradation correction data is selected. The appropriate gradation correction data is selected by first selecting a gradation correction table group in accordance with the detected electric potential distribution and second selecting a gradation correction data from the gradation correction table group in accordance with the detected density.

  • Patent number: 5404203
    Abstract: In an image-forming apparatus by using electrophotographic process, a method for stabilizing an image is provided. First, a photoconductor is sensitized with a prescribed standard sensitizing potential, and the surface potential thereof is detected. Then, the standard sensitizing potential is corrected according to the detected potential. Next, latent image patterns are formed with a plurality of light-emitting powers on a photoconductor which has been sensitized with the corrected prescribed standard potential, and the surface potentials thereof are detected. Thus, a relation between the light-emitting power and the surface potential is obtained directly. Then, the light-emitting power is determined which realizes the detected surface potential nearest to the object potential. Next, a standard toner image is formed for automatic image density control by using the corrected sensitizing potential and the selected light-emitting power.

  • Patent number: 5305057
    Abstract: In an electrophotographic image forming apparatus, a charger sensitizes the photoconductor at a desired initial potential and the photoconductor is exposed to form an electrostatic latent image, which is developed by a developer to form a toner image. A gradation correction table on the relation of the input image signal to the exposure amount is provided in a memory, and it is amended by adding a common amendment value to the image density signal in the gradation correction table. The common amendment value is determined according to the density of a standard toner image. If a plurality of gradation correction tables are stored in a memory, one of them is selected according to the output voltage of the charger or the bias potential of the developer. The selected gradation correction table is amended according to the surface potential of the photoconductor, the temperature of the photoconductor or the humidity of the photoconductor.

  • Patent number: 5274424
    Abstract: In an image forming apparatus with use of electrophotographic process, a plurality of toner images are formed on a photoconductor by changing stepwise a predetermined operating parameter such as light intensity of laser beam or the grid potential of sensitizing charger, and the densities of the toner images are measured. Thus, the value of the operating parameter is determined which corresponds with the smallest non-zero toner density among the measured densities. When an image is formed on the photoconductor, for example the gamma table is corrected according to the determined minimum light intensity.

  • Patent number: 4958191
    Abstract: A disconnecting mechanism or a driving force switching mechanism provided in a developing device functions so as to transmit a driving force from a driving source to a developer stirring mechanism only correlatively with a movement of each developing unit from a developer supply location adjacent to an image support member to a developer non-supply position away from the image support member. The disconnecting mechanism or the driving force switching mechanism functions so as to transmit a driving force from the driving source both to the developer stirring mechanism and a developing roll correlatively with the movement of each developing unit from the developer non-supply position to the developer supply location.
