发明名称 Image forming device having first and second light providing units
摘要 An image forming device, including a charging unit to electrically charge a surface of an 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 electrostatic latent image formed with a developer; a transfer roller to transfer an image developed by the developing unit to a recording paper; a light array having a plurality of light sources arranged in a predetermined pattern; a first light path providing unit to form a light path to receive a first light portion emitted from the light sources and to allow the light to be projected on the organic photoconductive medium between the developing unit and the transfer roller; and a second light path providing unit to form a light path to receive a second portion of the light emitted from the light sources and to allow the light to be projected onto the organic photoconductive medium passing through the transfer roller, thereby removing an electrostatic latent image remaining on the surface of the organic photoconductive medium.
