Abstract

A drum unit includes a photosensitive drum in a coupling member. The coupling member includes an engageable member having a driving force receiving portion which is capable of entering a recess of a driving shaft to receive a driving force for rotating photosensitive drum. The coupling member 5 includes a holding member configured to hold said engageable member so as to be slidable at least in a radial direction of said drum unit. [Figure 10]
