Abstract

A drum unit detachably mountable to a main assembly of an electrophotographic image forming apparatus includes a photosensitive drum and a coupling member provided on the photosensitive drum. The coupling member includes a driving force receiving portion and a supporting portion movably 5 supporting the driving force receiving portion. The supporting portion includes a first extended portion and a second extended portion which extend at least in an axial direction of the photosensitive drum. [FIGURE 13]
