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.
摘要:
A lubricant supply device includes a solid lubricant, a lubricant holder to hold the solid lubricant, a lubricant supply member to supply lubricant to a lubrication target, a pressing member to press the solid lubricant toward the lubricant supply member, and a pressing force adjuster to change an amount of pressing force exerted by the pressing member.
摘要:
In the present invention, a lubricant supplying device includes a lubricant end determining unit that determines that a solid lubricant is in an end state when the amount of a lubricant supplying operation reaches a threshold after a residual amount detecting unit detects that the residual amount of the solid lubricant is equal to or smaller than a predetermined amount. The lubricant end determining unit makes a threshold of the amount of the lubricant supplying operation at temperature or humidity of equal to or lower than a predetermined value lower than a threshold of the amount of the lubricant supplying operation at temperature or humidity of higher than the predetermined value.

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:
An image forming apparatus includes an image bearer to bear a toner image, a lubricant supply roller to supply lubricant to a surface of the image bearer, a rotation speed changer to change a rotation speed of the lubricant supply roller, and a controller to control the rotation speed changer to change the rotation speed of the lubricant supply roller to a target speed based on a predetermined condition. The controller is configured to control the rotation speed changer to avoid a predetermined speed range.
