PURPOSE: To effectively prevent toner from being dropped or scattered by storing a toner hopper in a bag-like case.

CONSTITUTION: The tonner hopper 33 is combined with the bag-like case 37 and completely stored in the case 37 and the case 37 is constituted so as to be tightly closed and optionally opened/closed. In case of using the toner hopper 33, a toner outlet 35 is exposed from the aperture 38 of the case 37 and the tonner hopper 33 is loaded to a copying machine under said status. In case of removing the toner hopper 33 from the copying machine, the aperture 38 of the case 37 is opened, and while covering or rupping the toner outlet 35 with/by the case 37 and holding the toner hopper 37 by a hand from the outside of the case 37, the tonner hopper 33 is removed from the copying machine body. Since the tonner dropped from the toner outlet 35 can be received by the case 37, pollution due to toner can be suppressed.
