Abstract
An image forming apparatus includes an image carrier, an exposure unit to form a latent image on the image carrier by light, and a particle entering prevention device to prevent particles from entering an optical path between the exposure unit and the image carrier. The particle entering prevention device includes a particle storage unit disposed in a vicinity of the optical path, to store the particles therein.
Claims23
An image forming apparatus, comprising:
- an image carrier;
- an exposure unit to form a latent image on the image carrier by light;
- and
- a particle entering prevention device to prevent particles from entering an optical path between the exposure unit and the image carrier,
- wherein the particle prevention device includes a particle storage unit disposed in a vicinity of the optical path, to store the particles therein.
An image forming apparatus, comprising:
- an image carrier;
- an exposure unit to form a latent image on the image carrier by light;
- and
- a particle storage unit disposed in a vicinity of an optical path between the exposure unit and the image carrier, to prevent particles from entering the optical path,
- wherein the particle storage unit has a larger width than a scanning width of light passing through the particle storage unit.
An image forming apparatus, comprising:
- a photosensitive member;
- an exposure unit to form a latent image on the photosensitive member by light;
- a frame unit having a light window disposed on an optical path between the exposure unit and the photosensitive member;
- and
- a particle storage unit to store particles in a vicinity of the light window, so as to prevent the particles from entering the light window.
A frame unit for an image forming apparatus, the frame unit comprising:
- a light window through which light scanned from an exposure unit of the image forming apparatus passes;
- and
- a particle entering prevention device to prevent particles from entering the light window,
- wherein the particle entering prevention device includes a particle storage unit disposed in a vicinity of the light window.
A particle entering prevention device usable with an image forming apparatus having a frame unit, a photosensitive member, an exposure unit and an optical path between the exposure unit and the photosensitive member, the particle entering prevention device comprising:
- a plurality of side members attached to opposite ends of the frame unit;
- a protruding wall disposed between the plurality of side members and to protrude from frame cover toward the photosensitive member;
- a film member in contact with and to shield a space between the protruding wall and the photosensitive member;
- and
- a plurality of sealing members interposed between two sides of the photosensitive member,
- wherein the particle entering prevention device prevents particles from entering the optical path.
