<P>PROBLEM TO BE SOLVED: To discharge toner without leaving it in a container as much as possible, while ensuring the capacity of the inside of the container body. <P>SOLUTION: A first straight internal surface 512A and second straight internal surface 513A of a first side wall 512 and second side wall 513, respectively, of a container main body 51 extend from the respective ends of a semicircular internal surface 511A in upward directions on the respective tangential lines. The space between the first straight internal surface 512A and the second straight internal surface 512B increases upward from a bottom wall 511. The first straight internal surface 512A on the upstream side in the rotating direction of a rotary member 54 is a substantially vertical internal surface in which a perpendicular extending right above a shaft center P of a rotary shaft 541 is slightly inclined inward relative to a reference line V. On the other hand, the second straight internal surface 513A is an inclined surface, inclined relatively greatly to the reference line V. That is, it is to be a first angle θ1<a second angle θ2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
