ABSTRACT:
An image forming apparatus employs an image carrier (photoreceptor) cartridge having protective covers of which surface is coated with conductive shield in order to prevent frictional charging that will bring on sparking between a photoreceptor and covers. Further, the photoreceptor cartridge is equipped on its surface with an elastic member which is a foam body having a plurality of foam cells for catching foreign matter such as paper particles in order to prevent the foreign matter from damaging the surface of the photoreceptor. Moreover, the photoreceptor cartridge is also equipped with a flick member for flicking off toner deposited on a conductive brush in order to prevent the brush from becoming dirty. Owing to the above-mentioned construction, the image forming apparatus can avoid degradation in image quality.
