PROBLEM TO BE SOLVED: To prevent developer from remaining in an upstream end in a developer conveyance direction, in conveying developer in an axial direction of a rotating member.SOLUTION: A toner cartridge 100 includes a cartridge body 102 that houses toner T, a rotating member 106 provided to be rotated in the cartridge body 102, a film material 108 having one end fixed to the rotating member 106 and a free end 108B obliquely protruding beyond the fixed end 108A with respect to the axial direction, and a fold-back part 110 which reinforces a side end part 108C of the film material 108. The fold-back part 110 reinforces the side end part 108C of the film material 108. A difference in rigidity between the upstream side and the downstream side (protruding side) of the film material 108 is increased, thereby increasing conveyance performance of the toner T and preventing the toner T from remaining on the upstream side. |
