PURPOSE: A photosensitive drum assembly and a process cartridge are provided to enable a twisted protruded unit of an insertion member to closely contact with two sides comprising an edge of a twisted hole, thereby maintaining the closely contacted status even in the delivery and non-delivery status of the driving force. CONSTITUTION: A support member (122) is arranged in one side of a photosensitive drum (110). An insertion member (121) is arranged in one side of the support member. The insertion member comprises a plurality of protruded unit (121a) which is able to be inserted into a twisted hole (181). The protruded unit closely contacts with at least a part of a cross section vertical to a driving shaft (180) and two sides of the twisted hole forming the edge of the twisted hole. |
