  • Publication number: 20060268342
    Abstract: The occurrence of uneven image density is presented, as well as image degradation caused by inhibiting the continuity of image density, produced by a photoreceptor in which uneven electrification exists, and additionally uneven sensitivity coexists without enlargement of the apparatus as well as increase in the cost. To the exposure amount obtained by the approximate linear transformation of the pixel gradation in each segment multi-divided in the surface of the photoreceptor drum, in all the pixel gradation including 0 level, an exposing source is controlled to exposure with the amount of exposure, offset with only the offset exposure amount Ea which corresponds to the difference between the initial electric potential and the reference initial electric potential V0 of the segment. The exposure amount adjustment of the offset exposure amount Ea is conducted by offsetting the exposure time in each pixel.

  • Publication number: 20050265053
    Abstract: An oscillator for ensuring the phase relationship between two resonant circuits coupled by a coupling circuit. A first resonant circuit outputs two signals having different phases, and a second resonant circuit outputs two signals having different phases. The coupling circuit includes a plurality of inverters connected in a ring manner, and couples the first resonant circuit and the second resonant circuit such that the two signals output from the first resonant circuit and the two signals output from the second resonant circuit have different phases. A filter is connected to the input side of each of the plurality of inverters. With this structure, a signal output from each of the plurality of inverters has either a phase lead or a phase lag according to the phase characteristics of the corresponding filter, and thus the phase relationship between the first resonant circuit and the second resonant circuit is ensured.

  • Patent number: 6965393
    Abstract: An image forming apparatus is provided that is capable of forming an image with excellent gradation quality without affected by variations in the sensitivity characteristic of the photoreceptor and the light quantity characteristic of the LED print head among individual products. A highest gradation appropriate exposure amount appropriate for the highest gradation is calculated from the sensitivity characteristic of the photoreceptor and the light quantity characteristic of the LED print head. Then, based on the highest gradation appropriate exposure amount, an appropriate lighting time of the LEDs that is appropriate for each gradation is calculated so that the increment of the exposure amount between the gradations including the first gradation, and the lighting times of the gradations are set based on the appropriate lighting times. Then, the LEDs are lit for the lighting time set in accordance with the gradation of the inputted image data.
