ABSTRACT:
To realize easier assembly of the photosensitive drum with appropriate contact force to the end face of the drum body, while restricting manufacture cost increase and avoiding need for high skill and/or experience for the factory worker who assembles the drum. A photosensitive drum for use in an electrophotographic image forming apparatus. The drum includes a cylindrical drum body11having a photosensitive layer, a pair of flanges12a,12battached to opposed end faces of the drum body, a reinforcing stay13provided inside the drum body, a drum shaft14for rotatably supporting the drum body via the flanges. The flanges are fixed to the reinforcing stay in such a manner that outer peripheries of the flanges are elastically contacted against the end faces of the drum body. Each flange includes, as a cantilever-like extension thereof, a fixing arm18for the reinforcing stay, a leading end of the fixing arm being fixed to the reinforcing stay with the fixing arm being elastically deformed toward the inside of the drum body, such that the fixing arm provides an elastic resilience for causing the outer periphery of the flange to be elastically contacted against the corresponding end face of the drum body.
