Abstract:
1. An image forming device comprising: an organic photoconductive medium; a charging unit to electrically charge a surface of the organic photoconductive medium; a light exposure unit to form an electrostatic latent image on the surface of the organic photoconductive medium; a developing unit to develop the formed electrostatic latent image with a developer; a transfer roller to transfer the developed image to a recording paper; a light array comprising a plurality of light sources arranged in a predetermined pattern to emit light; a first light path providing unit to provide a first light path to receive a first portion of the light emitted from the light sources and to allow the received first portion light to be projected on the photoconductive medium at a first position of the photoconductive medium between the developing unit and the transfer roller; a second light path providing unit to form a second light path to receive a second portion of the light emitted from the light sources and to allow the received second portion light to be projected onto the photoconductive medium passing through the transfer roller at a second position of the photoconductive medium, thereby removing the electrostatic latent image from the surface of the organic photoconductive medium; and a plate, between the photoconductive medium and the first light path providing unit, to prevent the developer from passing from the photoconductive medium to the first light path providing unit, wherein the first and second positions are on a same side of the photoconductive medium as the light array.
