Abstract
A photosensitive material drum capable of easily preventing the leakage of the adhesive through the notches which are for confirming the earthing of the flange member. The flange member inserted in an end portion of the drum body includes an annular protuberance covering an end surface of the drum body, and an insertion drum portion forming protruded portions so as to come in contact with the inner peripheral surface of the drum body and recessed portions maintaining a gap relative to the inner peripheral surface of the drum body alternately along the inner peripheral surface of the drum body. An adhesive is applied onto the inner peripheral surface of the drum body facing the recessed portions to prevent the turn of the flange member. Notches are formed in the annular protuberance for exposing the end surface of the drum body, the notches being formed at positions neighboring the protruded portions.
