摘要:
An image forming apparatus includes a waste toner conveying device including a primary conveyor to convey waste toner discharged from a plurality of primary cleaners and a secondary conveyor to convey waste toner discharged from a secondary cleaner. A relay conveyor conveys the waste toner discharged from the primary conveyor and the secondary conveyor. A waste toner container receives the waste toner discharged from the relay conveyor. The primary conveyor, the secondary conveyor, and the relay conveyor are disposed at one end of the image forming apparatus in a front-to-rear direction thereof. A secondary conveyor outlet of the secondary conveyor is disposed below a primary conveyor outlet of the primary conveyor and above an inlet of the waste toner container.

A lubricant supplying device includes: lubricant; a supplying member that supplies the lubricant to a lubricant supply target; and a remaining amount detecting unit that detects that a remaining amount of the lubricant is equal to or smaller than a certain amount. The remaining amount detecting unit includes a first electrode member and a second electrode member. The lubricant supplying device includes a member that causes at least a part of the second electrode member to move and causes the second electrode member to abut the first electrode member with an increase in consumption of the lubricant.

A lubricant applicator includes a solid lubricant, a lubricant applying member to apply the solid lubricant to a target object, a biasing member to bias the solid lubricant toward the lubricant applying member, and a regulating member to regulate the solid lubricant, which is biased toward the lubricant applying member by the biasing member, to prevent the lubricant from separating from the lubricant applying member by more than a predetermined distance. The regulating member is switchable between a regulating state for regulating the solid lubricant not to separate from the lubricant applying member by more than the predetermined distance and a non-regulating state.

A lubricant applicator includes a lubricant and a rotatable lubricant application member. The rotatable lubricant application member contacts the lubricant and an application target to apply the lubricant to the application target while rotating. The lubricant application member includes a core member, a first wound portion including a bristle member wound spirally around the periphery of the core member in a first direction, and a second wound portion including a bristle member wound spirally around the periphery of the core member in a second direction opposite the first direction in an axial direction of the core member. A process unit includes the lubricant applicator. A transfer device includes the lubricant applicator. An image forming apparatus includes at least one of the process unit and the transfer device and the lubricant applicator.

An image forming apparatus includes an image carrier, a charging device to charge a surface of the image carrier, disposed across a predetermined gap from the image carrier, a latent image forming device, a developing device to develop a latent image formed on the image carrier into a toner image, a transfer unit to transfer the toner image from the image carrier onto a recording medium, a cleaning member to clean the image carrier after the toner image is transferred therefrom, a lubricant application member to lubricate the image carrier, a polarity adjustor to adjust polarities of the toner and lubricant adhering to the image carrier to be identical to a polarity of a charging bias. The polarity adjustor is disposed facing the image carrier, upstream from the charging device and downstream from the transfer unit in a direction in which the image carrier rotates.

A waste-toner collecting device includes a waste toner collector that collects and stores therein non-transferred toner as waste toner conveyed from a cleaning unit via the conveying path; and a leveling member that levels waste toner accumulated inside the waste toner collector, and drive of which is controlled so that driving conditions thereof are varied based on information of an image formed on the image carrier. The switching of the driving conditions of the leveling member is controlled so as to be performed after a delay time during which the non-transferred toner collected in the cleaning unit reaches the waste-toner collector via the conveying path.
摘要:
A lubricating device operable to lubricate a moving imaging surface subsequent to removal of residual toner by a cleaning device includes a lubricant applicator, a metering blade, and a priming agent. The lubricant applicator is located downstream of the cleaning device in a direction of movement of the imaging surface, and applies lubricant to the imaging surface. The metering blade is located downstream of the lubricant applicator in the direction of movement of the imaging surface, and spreads the applied lubricant into a thin layer by directly contacting the imaging surface. The priming agent is prepared by mixing a lubricant and a powder, and provided, prior to initial operation, on the lubricant applicator for application to the imaging surface upon startup.

An image forming apparatus includes an image bearing member, a charging device to apply a charging bias, a developing device to develop a latent electrostatic image with toner, a transfer device to transfer the toner image to a recording medium, a fixing device to fix the toner image on the recording medium, an image formation speed switching device to switch from one image formation speed to another speed, a storage device to store a charging current target of the charging bias for each image formation speed, an electric current detection device to detect electric current flown through the charging device, and an AC voltage adjustment device to adjust AC voltage of the charging bias applied to the charging device. The charging current target is set for each of at least two image formation speeds such that each AC voltage adjusted by the AC voltage adjustment device is substantially the same.

A lubricant applicator rotatable at multiple different linear velocities, including a rotatable lubricant applying member to scrape a lubricant and to apply the lubricant to a surface of an image carrier rotatable at multiple different linear velocities. Any given linear velocity of the lubricant applying member satisfies a relation of n1/N1>n2/N2> . . . nx/Nx, where N1, N2, . . . Nx (N1
摘要:
A cleaning device for cleaning a surface of a rotatable image carrier includes a cleaning blade disposed to contact the image carrier and configured to remove toner on the surface of the image carrier, a lubricant applicator unit disposed above the cleaning blade, downstream from the cleaning blade in a surface rotation direction of the image carrier and configured to apply lubricant onto the surface of the image carrier, and an accumulation preventer configured to prevent the toner and excessive lubricant from the lubricant applicator unit from accumulating on the cleaning blade.
