摘要： A developing apparatus using a two-component developer constituted by a magnetic carrier and a toner, and an image forming apparatus comprising the developing apparatus. A developing unit and a stirring unit are provided, and in order to suppress toner scattering that may occur after a development operation has been halted for a long time, and thereby suppress contamination of the apparatus interior, the developer in a developing machine is transferred to a stirrer serving as a developer storage unit on the exterior of the developing machine when the development operation ends. Further, to extend the life of the developer, a range in which an angle of a restricting member upstream side central angle α, which is a central angle of the surface of a developing roller serving as a developer carrier on the upstream side of a restricting member opposing position opposing a doctor blade serving as a developer amount restricting member in a surface motion direction of the developing roller, is not less than 0[°] and not more than 60[°] is set as a low magnetic flux density area γ in which the maximum value of a normal direction magnetic flux density on the surface of the developing roller is not more than 30 [mT].

摘要： A developing device includes a developing unit, a developer agitating unit, a developer conveying unit, and a toner supplementing unit. The developing unit develops an electrostatic latent image on an image carrier with a developer containing toner and carrier. The developer agitating unit agitates the developer. The developer conveying unit connects the developing unit and the developer agitating unit, and conveys the developer from the developing unit to the developer agitating unit. The toner supplementing unit is connected to the developer conveying unit, and supplements toner to the developer conveyed from the developing unit to the developer agitating unit.

摘要： An agent transport unit for transporting an agent from a first container to a second container includes a transport route and a pump. The transport route connects the first container and second container, and includes at least one of a first route, a second route, and a third route. The first route extends in a substantially horizontal direction, the second route extends in a substantially vertical direction, and the third route extends in a substantially inclined direction with a repose angle equal to or less than that of the agent. The pump supplies a gas flow into the transport route to transport the agent in the transport route.

摘要： An image forming apparatus includes a conveying pipe configured to convey a developer and a magnetic field generation mechanism configured to generate a magnetic field inside the conveying pipe to affect the developer. The magnet is formed to have lower magnetic intensities at positions upstream and downstream from a middle position of the conveying pipe along a conveying direction of the conveying pipe than a magnetic intensity in the middle of the conveying pipe.
