<P>PROBLEM TO BE SOLVED: To provide: a toner cartridge capable of efficiently conveying toner in a toner storage chamber to outside; and a developing cartridge to which this toner cartridge is attached so as to be detachable. <P>SOLUTION: When a first agitator 55 further rotates after a first agitation blade 58 contacts a first interference member 56, a portion of a toner conveyance surface 58c, which is at the side of a fixed end 58a rotates prior to a portion of the toner conveyance surface 58c, which is in contact with the first interference member 56. As a result, the first agitation blade 58 is deformed such that a portion of the toner conveyance surface 58c, which is at the side of a free end 58b, is oriented toward a supply port 52 at the side of the cartridge, rather than the portion of the toner conveyance surface 58c, which is in contact with the first interference member 56. By rotating the first agitation blade 58 while deforming it, the component of force in the direction from the portion of the toner conveyance portion 58c, which is at the side of the free end 58b, to the supply port 52 of the toner conveyance surface 58c, which is at the side of the cartridge, is applied to toner between the portion of the toner conveyance portion 58c, which is at the side of the free end 58b, and the supply port 52 of the toner conveyance surface 58c, which is at the side of the cartridge. <P>COPYRIGHT: (C)2012,JPO&INPIT |
