Abstract: An image forming apparatus includes an image carrier, a developing device, a bias applying unit, a leakage detecting unit, a bias control unit and a leakage detection control unit. The developing device includes a magnetic roller and a developing roller. The magnetic roller carries a developer layer by being rotated. The developing roller receives the toner from the developer layer and supplies the toner to the image carrier. The leakage detection control unit performs a leakage detecting operation of detecting a value of an inter-peak voltage, at which the leakage occurred. The leakage detection control unit simultaneously starts the leakage detecting operation for a plurality of developing devices and performs the leakage detecting operations of the developing devices in which leakage simultaneously occurred while switching the leakage detecting operations one by one if the leakage simultaneously occurs in a plurality of developing devices at an inter-peak voltage.

Abstract: A developing device includes a development housing, a developer carrier, a toner carrier, a bias applying unit, a leakage detecting unit, a bias control unit and a leakage detection control unit. The developer carrier carries a developer layer. The toner carrier receives the toner from the developer layer and supplies the toner to an image carrier. The bias applying unit includes one transformer and applies direct-current voltages and alternating-current voltages to the developer carrier and the toner carrier. The leakage detecting unit detects leakage occurring between the image carrier and the toner carrier or between the toner carrier and the developer carrier. The leakage detection control unit detects a value of an inter-peak voltage at which the leakage occurs and determines whether the leakage occurs between the image carrier and the toner carrier or between the toner carrier and the developer carrier.

Abstract: A developing device includes: a housing, a refill developer storage part, a developing roller, a developer conveyance path, a developer receiving port, a conveyance member, and a magnetic member. The developing roller is driven into rotation in the developing housing and carries a toner on a circumferential surface thereof. The toner is conveyed inside the first conveyance path and the second conveyance path of the developing housing in a circulating manner. A first stirring screw is disposed on the first conveyance path and conveys the toner in a first direction. Downstream of the toner refill port, a magnet is arranged. The magnetic member forms a magnetic brush from a top panel of the developing housing towards the first stirring screw. A refill toner flowed-in through the toner refill port is so conveyed as to fall below the magnetic brush whereby the refill toner is favorably stirred with a surrounding toner.

Abstract: An image forming apparatus includes a developer, a development device, and an image bearing member. The developer includes an initial developer containing an initial carrier and a replenishment developer containing a replenishment carrier. The initial carrier has a surface roughness Sa1 of at least 0.3 μm and no greater than 1.0 μm. A ratio Sa1/Sa2 of the surface roughness Sa1 of the initial carrier to a surface roughness Sa2 of the replenishment carrier is at least 1.2 and no greater than 3.4. The packing volume Vp calculated from equation (1)“Vp=100×Y/(Z×DS)” was at least 40% and no greater than 70%. In equation (1), Y represents an amount of the developer conveyed by a developer bearing member. Z represents an apparent density of the initial developer. DS represents a width of a space between the developer bearing member and the image bearing member.
