PROBLEM TO BE SOLVED: To provide a cartridge capable of efficiently conveying developer.SOLUTION: A development cartridge 1 comprises: a toner storage part 5 storing toner; a development part 47 supporting the development roller 2; and a communication port 49 communicating the development part 47 with the toner storage part 5. An agitator shaft 61 of an agitator 6 inside the toner storage part 5 is horizontally biased by a compression spring 51, and an agitator blade 62 of the agitator 6 is made to contact with an internal surface of a bottom wall 36 of a development frame 31. Therefore, the agitator shaft 61 is pressed upward by the elasticity of the agitator blade 62, and the center of the agitator shaft 61 in a horizontal direction is bent in a direction pressed by the agitator blade 62 to displace, in a rotary direction R, the center 62BC and both ends parts 62BE of the agitator blade 62 in a horizontal direction. |
