<P>PROBLEM TO BE SOLVED: To provide a toner storage container which achieves cycles of cleaning and recycling after use of the vertical type toner storage container, permits the reutilization after use of the vertical type toner storage container, and can make a huge contribution to the saving of resource and energy and the reduction of an environmental load, and provide a toner supply device and an image forming apparatus having the container and device. <P>SOLUTION: The vertical type toner storage container, which is convergent in at least one slope heading toward a toner discharge port of the toner storage container having the toner discharge port on a lower side in the state of being set in the image forming apparatus, discharges toner from the toner storage container by the own weight of the toner or the pressure difference generated inside and outside of the toner storage container by a pressure releasing means having an air supplying means. The vertical type toner storage container has an inclination of ≥70° in the angle of the slop and the area of the toner discharge port is ≥30% in the area ratio to the top end of the slope. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
