초록 ▼

A developer circular unit is detachably set in a copier or a copier type printer which print on images on a paper sheet with toner. The unit includes at least a developing device, a cleaner, and a developer conveying device having a pipe communicated with both the cleaner and the developing device and a toner flowing-back preventing mechanism. The action of the mechanism is automatically released by the first set of the unit in the copier or printer and/or the first use of the copier or printer after that first set.

대표청구항 ▼

A developer restoring unit, which is detachably set in an image forming apparatus including an image bearing member, means for forming latent images on the image bearing member, means for developing the latent images on the image bearing member, means for transferring the developed images on the image bearing member to recording means, a cleaner for removing developer still left on the image bearing member after the image transferring process, and means for conveying developer from the cleaner to the developer means, said developer restoring unit comprising a combination of at least the developing means, the cleaner, and the developer conveying means, the developer conveying means including a pipe in communication with both the cleaner and the developing means, a developer conveying member located in the pipe to convey developer from the cleaner to the developing means, and means for preventing developer from flowing backward from the developing means to the cleaner through said pipe before the developer restoring unit is first used, said developer-backflow-preventing means being located at a developing-means-side end portion of said pipe, and including a shield mechanism for opening a developer discharge opening formed at said developing-means-side end portion of said pipe when said developer restoring unit is first set in the image forming apparatus, said shield mechanism including a thin seal for shielding said developer discharge opening and breaking means for striking against a body portion of the image forming apparatus when the developer restoring unit is first set in the imaging forming apparatus and for breaking said thin seal duel to the striking of said breaking means against said body portion.
