    • An optical writing device performs writing on an exposure region of a light writing display medium. The optical writing device includes an accommodation section, a light irradiation member, a voltage application member, a medium conveyance member and control means. The control means performs control for: applying voltage with the voltage application member to a first medium; the light irradiation member irradiating the light bearing image information and moving a first distance in the first direction over the first medium; the voltage application member applying voltage to a second medium; the light irradiation member irradiating the light for image erasure onto the second medium and moving a second distance in the second direction over the second medium; and, simultaneously the movement of the light irradiation member in the second direction, the medium conveyance member conveying the first medium.

    • There is provided an optical writing image forming device including: a positioning section positioning an optically written display medium including a pair of electrodes with at least one of which formed by a group of plural sub-electrodes, a display layer, and a photoconductor layer; a display layer initialization section applying an initialization voltage between the pair of electrodes and irradiating initialization light over the entire region of the photoconductor layer; an optical writing section; a head position identification section; and a writing information erasing section, based on information identified by the head position identification section, erasing in a time-series writing information in the display layer corresponding to the group of the plural sub-electrodes by selecting the sub-electrodes in sequence so that an image writing head does not obstruct light emitted from the initialization light source while the image writing head light source is being returned to a standby position.
    • 提供一种光写入图像形成装置,包括:定位部,定位包括一对电极的光学写入的显示介质,其中至少一个由一组多个子电极,显示层和感光体层形成; 显示层初始化部分,在所述一对电极之间施加初始化电压并在所述感光体层的整个区域上照射初始化光; 光学写作部分; 头位置识别部; 以及写入信息擦除部分,基于由头部位置识别部分识别的信息,通过依次选择子电极来擦除与多个子电极组对应的显示层中的时间序列写入信息,使得 当图像写入头光源正在返回到待机位置时,图像写入头不会阻挡从初始化光源发射的光。
