ABSTRACT:
A toner supply device includes a stopping member which moves into the toner supply port by interlocking with opening and closing of a shutter plate for opening and closing the toner supply port, and a scraper for scraping toner supplied from a toner container is pressed by the stopping member, thereby sliding in contact along the recessed portion of the toner container, thus restricting the rotation of the toner container. This restricts the rotation of the developer supply device due to user's operating error, preventing developer from spilling out from the developer supply port.
