摘要： A cleaning device includes a cleaning blade disposed in contact with a rotator, a toner collecting section disposed along the rotator and the cleaning blade and includes a groove extending in an axial direction of the rotator, a conveyor disposed in the groove, and an agitator disposed on a side of a rim of the groove. The conveyor rotates to convey the toner in a longitudinal direction of the groove. The agitator vibrates through contact with the conveyor and includes comb-tooth portions lined in a comb shape in the longitudinal direction of the groove, and bent portions, each of which is bent from an end of one of the comb-tooth portions. The comb-tooth portions contact a circumference of the conveyor to vibrate. The bent portions are lined at intervals smaller than intervals on a base side of the comb-tooth portions.

摘要： A toner conveyance device includes a downward passage, a reciprocating member disposed in the downward passage, to move in a vertical direction in which the downward passage extends, a conveyance passage communicating with a lower end of the downward passage and extending in a direction crossing the vertical direction, a conveyor to rotate in the conveyance passage around an axis extending along the conveyance passage to transport the toner, and a flexible member projecting from a bottom of the reciprocating member toward the conveyance passage. The flexible member extends in the axial direction of the conveyor and moves together with the reciprocating member. When the reciprocating member is at a lowest position, a lower end of the flexible member opposes a portion of the conveyor downstream from an upper end thereof in a rotation direction thereof.

摘要： 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.

摘要： An image forming apparatus includes a plurality of image forming units that are arranged in parallel so as to be opposed to an intermediate transfer belt or a transfer carriage belt. A black image forming unit that forms a black toner image is arranged at a downstream end or upstream end in the running direction of the intermediate transfer belt or the transfer carriage belt with respect to the other image forming units. The black image forming unit is configured so that its lubricant supplying unit contains a larger amount of lubricant.

摘要： An image forming apparatus including multiple image bearing members that bear respective electrostatic latent images, provided in tandem; multiple developing devices that develop the respective electrostatic latent images with toner to form respective toner images; an intermediate transfer member onto which the multiple toner images are transferred to form a composite toner image; multiple first lubricant applicators that apply a lubricant to the respective image bearing members; and a second lubricant applicator that applies a lubricant to the intermediate transfer member, provided upstream from the extreme upstream image bearing member. In this image forming apparatus, the amount of lubricant applied from the extreme upstream first lubricant applicator to the extreme upstream image bearing member is smaller than that applied from each of the other lubricant applicators to the respective image bearing members.
