Abstract: Provided is an image forming apparatus 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. An absolute value of a perpendicular-magnetic-force gradient of a fixed magnet of the developer carrying member is 4.0 mT/° or less at a position where the fixed magnet faces a central portion of the filter in a rotation direction of a developing sleeve.

Abstract: An imaging system includes a developing chamber, a first conveyance path, a second conveyance path, a first air passage and a second air passage. A developing roller located in the developing chamber carries a developer to a developing region where the developing roller is closest to an image carrier. A first stirring-conveying portion is located in the first conveyance path adjacent the developing roller to supply the developer to the developing roller. A second stirring-conveying portion is located in the second conveyance path adjacent the first conveyance path to circulate the developer between the second conveyance path and the first conveyance path. The first air passage has an inlet coupled to the developing chamber and an outlet coupled to the second conveyance path, and the second air passage has an inlet coupled to the second conveyance path and an outlet coupled to the developing chamber.

Abstract: An object of this disclosure is to reduce differences in the drawn amount of the parison around the mouth of the toner container, thereby reducing the amount of resin for the toner container and the weight thereof. A powder container includes a cylindrical container body to rotate in a horizontal posture, a cylindrical mouth at a first end of the container body, smaller in diameter than the container body, a conveyor to convey the powder inside the container body toward the mouth, a scooping portion deeper in the container body than the mouth, to lift the powder above a powder inlet of a conveying tube inserted from the mouth and drop the powder to the powder inlet, and a radially inner face continuous with an inner end of the scooping portion, extending in a direction crossing the scooping portion and disposed inward in the radial direction than an outermost face of the container body. The radially inner face extends from the mouth toward a second end of the container body and is not inner in the radial direction than an inner rim of the mouth.

Abstract: According to an embodiment, a developer-supplying container includes a container and a paddle. The container includes an opening for supplying the image forming apparatus with developer contained in the container. The paddle conveys the developer to the opening by rotating within the container. The paddle includes a first arm. The first arm has a shape that is wider on an upstream side in a direction of the rotation of the paddle and narrower toward a downstream side. In addition, the first arm is disposed such that a narrowest portion of the first arm is located at the same position as the opening in a direction of a shaft.

Abstract: A developer cartridge assembled to a developing device defining therein a developing chamber. The developer cartridge includes a first accommodating portion, and a first agitator. The first accommodating portion accommodates therein a developing agent and is positioned beside the developing device. The first accommodating portion includes a first wall part neighboring the developing device. The first wall part is formed with a first through-hole and a second through-hole. The first through-hole is open diagonally downward from the first accommodating portion to the developing device. The second through-hole is open diagonally upward from the first accommodating portion to the developing device. The first through-hole and the second through-hole allow communication between an interior of the first accommodating portion and the developing chamber. The first agitator is rotatably disposed in the first accommodating portion and in sliding contact with the first wall part in a vertical direction.
