<P>PROBLEM TO BE SOLVED: To provide a toner cartridge capable of maintaining high toner replenishing capability to a developing device and inhibiting occurrence of toner aggregation. <P>SOLUTION: The toner cartridge 200 includes a container body 205 and a screw conveyer means 208. The screw conveyer means 208 has a rotation shaft 201a and a toner conveying blade 201b. The rotation shaft 201a has a first rotation shaft portion 216a and a second rotation shaft portion 216b, which coaxially communicates with the first rotation shaft portion 216a and has a diameter smaller than that of the first rotation shaft portion 216a. The toner conveying blade 201b has a first blade portion 217a formed on the first rotation shaft portion 216a, and a second blade portion 217b formed on the second rotation shaft portion 216b, a period of a spiral 218b of the second blade portion being smaller than a period of a spiral 218a about the rotation shaft line of the first blade portion 217a. <P>COPYRIGHT: (C)2011,JPO&INPIT |
