<P>PROBLEM TO BE SOLVED: To provide a toner supply vessel allowing easy opening work of the toner supply vessel without soiling a hand. <P>SOLUTION: In this toner supply vessel 36Y, a coil screw 162 having a triple spiral section 162d is rotatably arranged in a toner supply vessel body 161 storing toner around the spiral axis of the triple spiral section 162d. By applying a rotation driving force to the coil screw 162, the toner in the toner supply vessel body 161 is sent in a predetermined direction, and is discharged from an opening 161c formed in a portion of the toner supply vessel body 161. The coil screw 162 includes shielding sections 162e, 162f and 162g for shielding the opening 161c from the inside of the toner supply vessel body 161 when the coil screw is at a predetermined rotation position. <P>COPYRIGHT: (C)2011,JPO&INPIT |
