Abstract

A toner transport device includes a toner transport path for passing toner, and a toner transport pipe disposed so as to have an up-and-down direction in which the toner transport path extends. Further, the toner transport device includes a pipe supporting member for supporting the toner transport pipe, which is supported so as to move up and down. This allows the toner transport pipe to vibrate up and down, thereby properly preventing retention and solidification of toner inside the toner transport path.
