To make a shutter plate properly execute a prescribed opening and closing operation at any time when attaching/detaching a toner supplying device to/from an image forming apparatus.
An outer locking claw 454 of a shutter plate 43 is formed so that an inner locking claw 453 can be removed from a container side locking groove 422 by elastic displacement of an elastic arm 44 due to an arrowhead member 45 fitted into a guide part-side locking groove 516, at the time when the arrowhead member 45 reaches the guide part-side locking groove 516 when mounting a container body 31 in an apparatus body 11 along a guide part 50. When the container body 31 is pulled out from the apparatus body 11 along the guide part 50, the inner locking claw 453 is engaged with the container-side locking groove 422 again by restoration of the elastic arm 44 which has been elastically displaced, by the engagement of the outer locking claw 454 being released with respect to the guide part-side locking groove 516.
