  • Publication number: 20100239279
    Abstract: A prediction table is stored in an NVM and an in-apparatus temperature is measured by a temperature sensor, a registration control adjustment based on the prediction table is carried out if an absolute value of a variation in the in-apparatus temperature is smaller than a threshold, and a registration adjusting patch is formed to actually measure a positional shift amount if the absolute value of the variation in the in-apparatus temperature is equal to or greater than the threshold. When the positional shift amount measured actually is greatly different from a value of the prediction table, the value of the prediction table is modified into the actually measured value.

  • Publication number: 20100239764
    Abstract: A tubular body 101 includes a layer containing a resin and conductive particles 112, the layer having a first region 111C that is free of conductive particles and lies at the outermost surface, and a second region 111B that has higher conductivity than other regions and lies closer to the innermost surface than the first region. A coating film of a coating liquid containing the conductive particles and resin material is dried, and then an eluting solvent for eluting the resin material from the film is applied thereto. As a result of this, the conductive particles are localized in the coating film at the side coated with the eluting solvent. Thereafter, upon drying the eluting solvent, the resin material dissolved in the eluting solvent deposits on the region where the conductive particles are localized, whereby a particle-free resin region free of the conductive particles is formed.

  • Patent number: 7800795
    Abstract: An original comprises a first page and a second page as disposed face-down on the platen surface of an image-processing device. The platen is scanned to form a platen image. The positions of two diagonally-opposite corners of the original are determined based on a fixed platen reference point. An original image is formed by cropping the platen image based on the positions of the two original corners. The size and position of either one selected page or both pages are determined based on the two original corner positions. When the image of only one selected page is desired, the image of the selected page is formed by cropping the original image based on the size and position of the selected page. When the images of both pages are desired, the images of both pages are formed by cropping the original image based on the sizes and positions of both pages.
