  • Patent number: 5850585
    Abstract: A destaticizer which is adapted to remove electric charges from the surface of a photoreceptor by exposing the photoreceptor surface to light. The destaticizer includes a light source, and a light guide member for generally uniformly guiding light from the light source to a light exposure area on the photoreceptor. In accordance with one embodiment, the light guide member is an elongated member, which has an end face serving as a light receiving face for receiving the light emitted from the light source, a light transmitting path for transmitting the light received by the light receiving face, and a plurality of reflecting portions arranged along the length of the light guide member for reflecting the light transmitted through the light transmitting path in a direction intersecting the length of the light guide member.
