  • IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD
    Publication number: 20130272728
    Abstract: An apparatus includes an image formation unit including a photosensitive drum and a motor for driving the image formation unit. The apparatus acquires a frequency generator signal, which is phase information output from the motor as the motor rotates. In addition, the apparatus corrects unevenness of the density that may occur due to the rotation of the motor according to the acquired phase information.
    Type: Application
    Filed: June 11, 2013
    Publication date: October 17, 2013
    Inventors: Takayuki Fukutani, Yuuji Takayama, Tomoyuki Saiki, Tae Mutsuo, Yuichi Ogawa
  • Apparatus and method for image forming including density correction according to a phase based on correction information
    Patent number: 8483587
    Abstract: An apparatus includes an image formation unit including a photosensitive drum and a motor for driving the image formation unit. The apparatus acquires a frequency generator signal, which is phase information output from the motor as the motor rotates. In addition, the apparatus corrects unevenness of the density that may occur due to the rotation of the motor according to the acquired phase information.

  • Image forming apparatus, image forming method, and program
    Patent number: 8358443
    Abstract: The image forming apparatus includes a halftone processing section that executes halftone processing having a halftone processing period, a signal add-on section that adds the add-on signals on the input image signals subjected to the halftone processing, a position information acquisition section that acquires position information to determine a relative position of halftone dots by the halftone processing and the add-on signals in a first image area, the first image area is based on a common multiple of the halftone processing period and a minimum interval of the add-on dots, and the position information preventing the add-on signals added by the signal add-on section from crossing over the halftone dots, and an add-on control section that continues or repeats add-on control processing of the add-on signals, executed based on the acquired position information, in a second image area based on the common multiple and consecutive from the first image area.
