Zusammenfassung:	A process cartridge includes a drum cartridge that has a drum frame having a a second end portion spaced apart from a first end portion in a first direction and a fourth end portion spaced apart from a third end portion in a second direction, a photosensitive drum rotatable about a first axis extending in the second direction and positioned at the first end portion of the drum frame, and a first storage medium that includes a first electrical contact surface. A developing cartridge is detachably attachable to the drum frame and has a developing roller that is rotatable about a second axis extending in the second direction and a second storage medium including a second electrical contact surface. The first electrical contact surface is positioned closer to the second end portion of the drum frame than the photosensitive drum is to the second end portion of the drum frame in the first direction, and in a state where the developing cartridge is attached to the drum cartridge, the second electrical contact surface is positioned closer to the second end portion of the drum frame than the photosensitive drum is to the second end portion of the drum frame in the first direction.
