ABSTRACT:
A developing cartridge includes a housing having a photosensitive medium, and a protective cover movable between a first position where the protective cover covers the photosensitive medium and a second position where a part of the photosensitive medium is exposed. A guide unit guides the protective cover to prevent exceeding a range occupied by the housing when the protective cover is moved to the first and second positions.
