Abstract
There is provided a light guide body that extends in a rod shape and guides light incident from an end surface thereof to emit the light from a circumferential surface thereof, the light guide body having a shape such that according to an angle of a circumferential direction around the light guide body, an amount of emitting light in a directoin of the angle is different. There is also provided a static elimination device and an image forming apparatus which include the light guide body.
Claims6
A light guide body that extends in a rod shape and guides light incident from an end surface thereof to emit the light from a circumferential surface thereof, the light guide body having a shape such that according to an angle of a circumferential direction around the light guide body, an amount of emitting light in a directoin of the angle is different.
A static elimination device comprising:
- a light guide body that extends in a rod shape, is disposed along a static elimination object body which is irradiated with light to be neutralized and guides light incident from an end surface thereof to emit the light from a circumferential surface thereof;
- a light source that emits light to be incident on the end surface of the light guide body;
- and
- a reflector that is formed with an opening on a facing surface side facing the static elimination object body, surrounds an area of the light guide body except the facing surface side of the light guide body, and reflects the light emitted from the light guide body,
- wherein the light guide body has a shape such that according to an angle of a circumferential direction around the light guide body, an amount of emitting light in a direction of the angle is different.
An image forming apparatus comprising:
- an image holding member that is formed thereon with an electrostatic latent image while rotating about a rotation axis thereof, holds a toner image developed at a developing position and transfers the toner image to a transfer destination at a transfer position;
- a developing device that develops the electrostatic latent image on the image holding member at the developing position to form the toner image on the image holding member;
- a transfer unit that transfers the toner image on the image holding member onto the transfer destination at the transfer position;
- and
- a static eliminator that is disposed in a proximity of an area on the image holding member after transferring and neutralizes the image holding member by irradiating the area with light, and
- wherein the static eliminator comprises:
- a light guide body that extends in a rod shape, is disposed along the image holding member and guides light incident from an end surface thereof to emit the light from a circumferential surface thereof, the light guide body having a shape such that according to an angle of a circumferential direction around the light guide body, an amount of emitting light in a directoin of the angle is different;
- a light source that emit light to be incident on the end surface of the light guide body;
- and
- a reflector that is formed with an opening on a facing surface side facing the image holding member, surrounds an area of the light guide body except the facing surface side of the light guide body, and reflects the light emitted from the light guide body.
