Abstract
A drum cartridge includes a first photosensitive drum, a frame, a first toner cartridge connector, a first harness, and a protection wall. The first photosensitive drum is rotatable about a first drum axis extending in a first direction. The first harness is electrically connected to the first toner cartridge connector. The first harness extends in a second direction intersecting the first direction. The protection wall extends in the second direction and positioned between the inner surface of the first side plate and the second side plate. The first harness is received between the protection wall and the inner surface of the first side plate.
