Abstract
A toner bottle for containing toner has a cylindrical body and a scraper. The bottle body can be rotated on its axis by a driving source. The scraper is supported movably in the bottle body. The bottle body has an opening and ribs. The toner in the toner bottle is supplied through the opening to a developing unit. When the bottle body rotates, the ribs convey the toner toward the opening. The scraper includes a shaft and a scraping part. The shaft extends over the whole length of the bottle body and supports the scraping part. A portion of the scraping part is in contact with the inner cylindrical surface of the bottle body. When the bottle body rotates, the scraper moves perpendicularly to the axis of the body.
