Title: DRUM CARTRIDGE AND PROCESS CARTRIDGE
Abstract:
A structure is provided in which the electrical contact surface of a storage medium is disposed on the outer surface of a drum frame, and the electrical contact surface can contact the electrical terminal of an image formation device even when a developing cartridge is mounted. The drum cartridge has a drum frame 21 on which a developing cartridge can be mounted, a photosensitive drum, and a first storage medium 29. The developing cartridge can be mounted on the drum frame 21. The photosensitive drum is positioned at one end 211 of the drum cartridge in a first direction. The first storage medium 29 has a first electrical contact surface. The first electrical contact surface is positioned on the exposed outer surface of the drum frame 21 when the developing cartridge is mounted on the drum frame 21. It is thereby possible to bring the first electrical contact surface into contact with the electrical terminal of the image formation device even when the developing cartridge is mounted.
