An image forming apparatus includes a main body housing, a drum cartridge, and a toner cartridge. The drum cartridge is movable inside the main body housing between a drum first position and a drum second position. The toner cartridge is movable between a toner first position and a toner second position in a state where the toner cartridge is coupled to the drum cartridge. In a state where the toner cartridge is coupled to the drum cartridge, the drum cartridge is at the drum second position, and the toner cartridge is at the toner second position, the toner cartridge is pivotally movable relative to the drum cartridge between a first pivot position at which coupling of the toner cartridge to the drum cartridge is not releasable and a second pivot position at which the coupling of the toner cartridge to the drum cartridge is releasable.
