Abstract
A process and an apparatus for cleaning an organic photosensitive drum in an image forming apparatus including a developer housing formed with an exposure window at a desired portion thereof and contained therein with an organic photosensitive drum, a developing roller, and a charging roller, the developing roller being configured to recover toner particles left on an outer surface of the organic photosensitive drum, for reuse thereof. The drum cleaning apparatus includes a cleaning film arranged between the charging roller and the exposure window while being in contact with the outer surface of the organic photosensitive drum, the cleaning film serving to remove foreign matters affixed to the outer surface of the organic photosensitive drum.

In an image forming apparatus including a developer housing formed with an exposure window at a desired portion thereof and contained therein with an organic photosensitive drum, a developing roller, and a charging roller, the developing roller being configured to recover toner particles left on an outer surface of the organic photosensitive drum for reuse thereof, an apparatus for cleaning the organic photosensitive drum comprising:
- means arranged between the charging roller and the exposure window while being in contact with the outer surface of the organic photosensitive drum, the means serving to remove foreign matter affixed to the outer surface of the organic photosensitive drum.
An image forming apparatus, comprising:
- a developer housing formed with an exposure window;
- an organic photosensitive drum located within said housing;
- a developing roller configured to recover toner particles left on an outer surface of the organic photosensitive drum for reuse located within said housing;
- a charging roller located within said housing;
- and
- an apparatus for cleaning said organic photosensitive drum, comprising a blade positioned between said charging roller and said exposure window while a distal end of said blade is in contact with said outer surface of said organic photosensitive drum, said housing orienting said blade to engage and remove from said outer surface foreign matter adhering to said outer surface of said organic photosensitive drum.
An image forming apparatus, comprising:
- a developer housing formed with an exposure window;
- an organic photosensitive drum located within said housing;
- a developing roller positioned to recover toner particles from an outer surface of the organic photosensitive drum for reuse located within said housing;
- a charging roller located within said housing;
- and
- a blade positioned between said charging roller and said exposure window while a distal end of said blade engages said outer surface of said organic photosensitive drum, said developer housing orienting said blade to form a tangent to said outer surface along an axial line where said distal end engages said outer surface and remove foreign matter adhering to said outer surface of said organic photosensitive drum.
