Abstract: A developer conveying device includes a housing, a developer conveyance path and a conveying member. The developer conveyance path extends between a pair of wall portions. The conveying member includes a spiral member, an inner wall portion and shaft portions. The spiral member is formed by connecting spiral pieces, each forming one spiral turn, in a conveying direction of the developer and includes a hollow interior formed by the connected spiral pieces. The inner wall portion includes a plurality of planar portions which define the hollow interior of the spiral member and are connected at predetermined angles in a circumferential direction of the rotation of the conveying member. The shaft portions are arranged at opposite end parts of the spiral member, rotatably supported on the wall portions and serve as a rotary shaft for the rotation of the conveying member.

Abstract: A developer conveying device includes a housing, a developer conveyance path and a conveying member. The developer conveyance path extends between the pair of wall portions of the housing. The conveying member conveys developer from one wall portion toward the other. The conveying member includes a spiral member, shaft portions, a rib member, a supporting member and a projecting portion. The spiral member is formed by connecting spiral pieces in a conveying direction of the developer and includes a hollow interior formed by the connected spiral pieces. The rib member extends in the conveying direction and bridges adjacent ones of the spiral pieces of the spiral member. The supporting member connects an end part of the rib member in the conveying direction and the shaft portion. The projecting portion projects from the end part of the rib member more toward the wall portion than the supporting member.

Abstract: Provided is an image forming apparatus that is capable of carrying out a scattered-toner recovery mode in which, while image formation is prevented from being performed, scattered toner that has dropped from a filter and adhered to an outer peripheral surface of a developer carrying member is recovered by a cleaning unit through intermediation of an image bearing member. A fixed magnet of the developer carrying member has a first pole that faces the image bearing member, a second pole that faces the filter, and an intermediate pole between the first pole and the second pole.

Abstract: An image forming apparatus includes a development device, and a control unit that controls the development device. The development device includes a toner collection mechanism having a duct, a filter, and an exhaust fan. The duct is connected to a conveyance chamber of the development container and allows air in the conveyance chamber to flow through. The filter is disposed at a connecting part between the duct and the conveyance chamber, and collects toner flowing into the duct from the conveyance chamber. The exhaust fan makes the air in the conveyance chamber flow to the outside via the duct. The control unit changes rotational frequency or operation frequency of the exhaust fan based on current detected by a current detection unit at non-image forming time.

Abstract: A developing device includes a developing roller, a regulating blade, and seal members. The regulating blade extends in a rotation axis direction of the developing sleeve, is disposed opposite to a circumferential surface of the developing sleeve, and regulates a quantity of the toner present on the circumferential surface of the developing sleeve. The seal members are disposed opposite to the circumferential surface of the developing sleeve without being in contact with both ends of the developing sleeve in the rotation axis direction, and inhibit the toner on the circumferential surface from moving to the rotation axis direction ends by magnetic brushes formed between the magnet roller and the seal members. An inner surface part of each seal member which is opposite to the circumferential surface of the developing sleeve has root parts which have crest parts formed in a serrated shape.
