Abstract
An image forming apparatus includes a main assembly, and a supporting member capable of supporting a plurality of developing rollers and a plurality of photosensitive drums, with the supporting member being movable substantially linearly between an inside position inside of the main assembly and an outside position outside of the main assembly while supporting the developing rollers and the photosensitive drums. In addition, a plurality of developing cartridges each have the developing roller and are mountable to and dismountable from the supporting member which supports the plurality of photosensitive drums when the supporting member is in the outside position. The developing cartridges each include an upper surface facing upward when mounted to the supporting member and a projection projecting upwardly from the upper surface and having a shape providing a space through a middle portion thereof.
