Abstract
An image forming apparatus is provided. The image forming apparatus includes a photosensitive member; and an exposure member having a light emitting element, the exposure member exposing the photosensitive member at an exposure position opposed to an opposed position on the photosensitive member to form the electrostatic latent image, the exposure member being movable between the exposure position and a retreated position retreating from the exposure position, wherein the exposure member includes a dust-proof wall protruding more than a light-emitting surface of the exposure member and a positioning member positioning the exposure member with respect to the photosensitive member at the exposure position, and wherein the dust-proof wall and the positioning member are integrally formed.
Claims13
An image forming apparatus comprising:
- a photosensitive member in which an electrostatic latent image is formed on the surface thereof;
- and
- an exposure member having a light emitting element, the exposure member exposing the photosensitive member at an exposure position opposed to an opposed position on the photosensitive member to form the electrostatic latent image, the exposure member being movable between the exposure position and a retreated position retreating from the exposure position,
- wherein the exposure member includes
- a dust-proof wall protruding more than a light-emitting surface of the exposure member, and
- a positioning member positioning the exposure member with respect to the photosensitive member at the exposure position,
- wherein the dust-proof wall and the positioning member are integrally formed, and
- wherein the dust-proof wall is separate from the photosensitive member when the exposure member is disposed at the exposure position.
An image forming apparatus comprising:
- a photosensitive member;
- an exposure member having a light emitting element, a dust-proof wall protruding more than a light-emitting surface of the exposure member and a positioning member positioning the exposure member with respect to the photosensitive member at an exposure position;
- and
- a frame supporting the photosensitive member and having a through hole into which the dust-proof wall is inserted at the exposure position;
- wherein the dust-proof wall and the positioning member are integrally formed,wherein the dust-proof wall and the positioning member are disposed in the light-emitting surface side of the exposure member, and
- wherein when the exposure member is positioned at the exposure position, the positioning member contacts on the frame.
