Abstract: A scanning device is provided to improve printing quality of a scanned manuscript and reliability of a product by outputting no dark image caused from scanning of a non-image area and exposing no light of a scanning unit to a user even if the scanning unit is operated in a state that a cover is not completely closed. A scanner body(110) is equipped with a manuscript table(111) for receiving the manuscript. The scanning unit(120) scans the manuscript by being movably installed to the inside of the scanner body. The first and second shielding film covers the non-image area of the manuscript table. The first storing reel(141) and the second storing reel respectively/elastically wind up and store the first and second shielding film. A holding unit keeps the state that the first and second shielding film covers the non-image area. The first shielding film(131) covers a vertical direction of the non-image area and the second shielding film covers a horizontal direction of the non-image area. The first and second shielding films are installed and have different heights each other to prevent interference between the first and second shielding film.

Abstract: A developing apparatus is provided to rotate a limitation roller as much as a predetermined angle, thereby maintaining the design lifetime and reducing the environmental contamination. A photosensitive drum is rotatably installed at a housing and electrified with a predetermined voltage by an electrification roller. A predetermined latent image is formed by a laser beam emitted by an exposure unit. A developing roller is rotatably installed at the housing with the contact or non-contact type and supplies the toner received from a toner hopper to the photosensitive drum so that the latent image is formed. A limitation roller is installed at a side of the developing roller between the photosensitive drum and a toner hopper at the inside of the housing.
