<P>PROBLEM TO BE SOLVED: To prevent mixing with foreign matters. <P>SOLUTION: The powder storage container includes: a powder storage container body that stores powder and has a powder supply port for supplying the powder; and a shutter 42 having a shutter member that is disposed so as to freely rotate with respect to the powder storage body and opens or closes the powder supply port according to the rotation. The shutter 42 has a restricting element for restricting rotation of the shutter member when the powder supply port faces upward. Since the rotation of the shutter member is restricted when the powder supply port faces upward, this prevents powder supply port from being opened accidentally. Accordingly, mixing with foreign matters such as paper powder, in the powder storage container can be prevented. <P>COPYRIGHT: (C)2010,JPO&INPIT |
