Abstract:
A drum unit includes: a frame; a first photosensitive drum; a second photosensitive drum; a charger; and a storage medium. The frame includes: a first frame plate; a second frame plate spaced apart from the first frame plate in a first direction; a third frame plate connecting one end of the first frame plate to one end of the second frame plate; and a fourth frame plate connecting another end of the first frame plate to another end of the second frame plate. The first photosensitive drum and the second photosensitive drum are rotatably supported by the frame. The second photosensitive drum is spaced apart from the first photosensitive drum and positioned closer to the third frame plate than the first photosensitive drum to the third frame plate in a second direction. The storage medium has an electrical contact surface positioned at an outer surface of the fourth frame plate.

Claim (Index 11):
The drum unit according to  claim 10 , further comprising an elastic member positioned between the outer surface of the fourth frame plate and the electrical contact surface, the elastic member being configured to expand and contract between a first state and a second state, the elastic member at the first state having a first length between the fourth frame plate and the electrical contact surface, the elastic member at the second state having a second length smaller than the first length between the fourth frame plate and the electrical contact surface, the elastic member being in the first state in a state where the electrical contact surface is separated from a device-side contact of an image forming apparatus, the elastic member being in the second state in a state where the electrical contact surface is in contact with the device-side contact.
