くテンションがかかつている。FIG. 1 shows a toner replenishing device for an electrophotographic printer according to the present invention. In FIG. 1, toner is supplied to a case body 1 through a toner supply port 2 and capped with a toner cap 3. The bottom opening 1a of the case body 1 is equipped with a shutter 4 held by a slide guide 5 so as to be openable and closable. A spring 8 is hooked between a side hook 6 attached to the slide guide 5 and a side hook 7 attached to the case body 1, and tension is applied to always slide the shutter 4 in the direction of the arrow in the open state.
