  • Publication number: 20060251438
    Abstract: A method and an apparatus of controlling a charge voltage including the steps of applying, charging, detecting, and determining. The applying step applies an application voltage having a direct-current voltage and an alternating-current voltage superimposed onto the direct-current voltage to a charge-applying member to charge a charge carrier. The changing step charges the alternating-current voltage of the application voltage. The detecting step detects an alternating current flowing through the charge carrier when the charge-applying member applies the application voltage to the charge carrier. The determining step determines a value of the alternating-current voltage of the application voltage based on at least two alternating currents detected by the alternating-current detector.

  • Patent number: 7110699
    Abstract: An image forming apparatus of the present invention includes a sheet affixed at one edge portion and including a flat surface in the other edge portion. The flat surface is formed with a plurality of grooves each extending over the image forming range of a photoconductive drum perpendicularly to the direction in which the surface of the drum moves. The sheet is deformed such that the flat portion contacts the surface of the drum. In this condition, the downstream edges of the grooves in the above direction shave off the surface of the drum a plurality of times during one rotation of the drum, thereby obviating filming on the drum.

  • Publication number: 20060120741
    Abstract: An image forming apparatus, incorporating a process cartridge, capable of determining optimum light exposure conditions suitable for both a charging potential and a film thickness of image bearing member, and performing the image formation even during the period from initiating to completing the setting of light exposure conditions. The image forming apparatus includes at least a charger unit, a light exposure unit, a developer unit, a detection unit, and a control unit. The detection unit is adapted to detect the total of rotation of the image bearing member. The control unit computes light exposure conditions to operate the light exposure unit based on an estimated thickness for a film of the image bearing member, which is calculated from the total of rotation obtained by the detection unit, and a first target uniform charging potential to control a uniform charging potential of the image bearing member, and to control the light exposure unit to be brought into the light exposure conditions.
