ABSTRACT:
A cleaning apparatus and an image forming apparatus including the same. The cleaning apparatus includes: a developing unit to supply toner to an electrostatic latent image formed on a photosensitive body, a cleaning blade installed above the photosensitive body and the developing unit to contact a circumference of the photosensitive body along a lengthwise direction thereof with a predetermined force, to remove waste toner remaining on the photosensitive body, and having a surface along which the removed waste toner is transported, and a waste toner reservoir unit to store the waste toner transported along the surface after being removed by the cleaning blade, wherein the surface slopes upward at a predetermined angle with respect to a horizontal plane. The cleaning apparatus efficiently utilizes space in the image forming apparatus and can protect the photosensitive body and the developing unit from being deformed by external impact. The cleaning apparatus has a simple structure because it does not include an additional waste toner transporting device and can be manufactured at low costs.
