<P>PROBLEM TO BE SOLVED: To provide a toner cartridge having stable performance, in which the flocculation of toner is less likely to occur. <P>SOLUTION: The toner cartridge is held so that a projecting part 76B on a side, to which a toner supply port 84 is provided is made the bottom, flow in the direction as shown by an arrow in a Figure is generated in toner T inside the cartridge, at transport. That is, the toner T inside the cartridge starts to flocculate, in the direction of gravity due to minute vibrations at transport conveyance; but since the toner T tends to flow in the direction of greater volume, when the projection part 76B is made the bottom, excessive toner flocculation at projection parts 76A and 76B can be prevented, since the toner T is moved more easily to a large-capacity part (right side in the Figure) above the projecting part 76B, up to a boundary wall 75B part (central part 74). <P>COPYRIGHT: (C)2008,JPO&INPIT |
