Claim:
An image forming apparatus comprising: a main body casing; a holder configured to move between an accommodated position where the holder is accommodated in the main body casing and a pulled out position where the holder is pulled out from the main body casing; a plurality of photosensitive drums held by the holder and juxtaposed with each other with an interval between neighboring photosensitive drums; a plurality of developing units held by the holder and each corresponding to each photosensitive drum to develop the corresponding photosensitive drum; and a plurality of toner cartridges configured to be attached to the holder when the holder is in the pulled out position, each of the plurality of toner cartridges corresponding to one of the plurality of developing units to supply toner, each of the toner cartridges comprising: a case configured to contain the toner therein and having an opening at a position confronting the corresponding developing unit in a state that the toner cartridge is attached to the holder; a shutter movable between a block position where the shutter blocks the opening and an open position where the shutter opens the opening; and an operation member for operating the shutter such that the shutter moves between the block position and the open position, the shutter being located at the open position when the operation member is located at a first position, the shutter being located at the block position when the operation member is located at a second position different from the first position, the operation member having: a base end fixed to the shutter; and a distal end configured to move from a lower position to a higher position higher than the lower position when the operation member is moved from the first position to the second position, wherein the holder is configured to move in a moving direction directed from the pulled out position to the accommodated position, wherein, for each of the plurality of toner cartridges, a direction directed from the base end to the distal end is parallel to the moving direction when the operation member is located in the first position, and wherein, for each of the plurality of toner cartridges, the distal end is located at a position higher than the base end when the operation member is located in the second position.
