Abstract
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.
