Abstract
A developing device includes a developer storing unit that stores a developer before use of the developing device, a developer containing unit that contains, when the developing device is used, the developer stored in the developer storing unit such that the developer is capable of being stirred by the developer containing unit, a developer holding unit that is provided in a portion of the developer containing unit and that holds the developer contained in the developer containing unit and moves the developer in a rotation direction, a sealing unit including a sealing tape portion that seals a slit-shaped opening formed in the developer storing unit along a longitudinal direction of the developer storing unit while the sealing tape portion is capable of being pulled out and that seals the slit-shaped opening of the developer storing unit by being removably fixed onto an edge of the opening and an extended tape portion that is folded at an end of the sealing tape portion in a longitudinal direction of the sealing tape portion and that extends along the sealing tape portion in such a manner as to project outward beyond the sealing tape portion, a scraping unit that is disposed at an end portion of the developer storing unit in the longitudinal direction and that causes the extended tape portion of the sealing unit to move while making frictional contact with the scraping unit so as to scrape off developer powder deposited on the extended tape portion and on the sealing tape portion, which follows movement of the extended tape portion, and a holding unit that is disposed outside the scraping unit in the longitudinal direction of the developer storing unit with a space formed between the holding unit and the scraping unit and that holds the extended tape portion and the sealing tape portion such that the extended tape portion and the sealing tape portion are capable of moving.
