20090241830LUBRICANT APPLYING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A lubricant applying unit has a residual-toner collection rate X of 50% when the lubricant applying unit has not been used. The collection rate X is obtained by X=(Ta−Tb)/Ta×100, where Ta is weight per unit area of the residual toner on an area of the image carrier that has not come into contact with the lubricant applying unit, and Tb is weight per unit area of the residual toner on an area of the image carrier that has come into contact with the lubricant applying unit.10-01-2009
20110076075Lubricant applicator, image forming apparatus, and method of mounting lubricant applicator - A lubricant applicator includes: a lubricant application unit that is arranged so as to be in contact with a surface of an image carrier, scrapes a solid lubricant, and applies the solid lubricant onto the surface of the image carrier while moving a surface of the lubricant application unit; a lubricant holding member that holds the solid lubricant; and a lubricant biasing unit that biases the solid lubricant against the lubricant application unit. The lubricant biasing unit is housed in a housing under a state that one end of the lubricant biasing unit is held by the lubricant holding member so that a position of the one end of the lubricant biasing unit is restricted, and another end of the lubricant biasing unit is held by a biasing-unit holding member that is provided to restrict a position of the another end of the lubricant biasing unit.03-31-2011
20110097124Waste-toner collecting device, process cartridge, and image forming apparatus - 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.04-28-2011
20110123239Lubricant applicator, process unit including the lubricant applicator, transfer unit including the lubricant applicator, and image forming apparatus including the process unit or the transfer unit - 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.05-26-2011
20110217101Lubricant applying device, process cartridge, and image forming apparatus - A lubricant applying device includes a solid lubricant, and a rotatable applying member scraping lubricant off the solid lubricant and applying the scraped lubricant onto an application subject. In the lubricant applying device, a pressing unit applies that applies an applying pressure of pressing the solid lubricant against the applying member and that varies the applying pressure in accordance with a rotation speed of the applying member.09-08-2011
20110274474Lubricant applicator, process cartridge, transfer unit, and image forming apparatus - 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.11-10-2011
20110311277Image forming apparatus and process cartridge incorporated therein - A tandem-type electrophotographic image forming apparatus includes multiple color image forming units using a dry toner, a first black image forming unit using the dry toner, and a second black image forming unit using a wet toner and performs an image formation with the dry toner in a first printing mode and an image formation with the wet toner in a second printing mode. The image formed in the second printing mode with the wet toner is fixed to a recording medium at a temperature lower than the image formed in the first printing mode with the dry toner. Each of the image forming units corresponds to a process cartridge that is removably installable in the tandem-type electrophotographic image forming apparatus and including an image carrier and other image forming components integrally therein.12-22-2011
20120014728Waste toner container and image forming apparatus incorporating same - A waste toner container used in an image forming apparatus includes a waste toner reservoir extending in a depth direction of the image forming apparatus for containing waste toner removed from an image bearer, an inlet portion provided above the waste toner reservoir, including a waste toner inlet to receive the waste toner flowing to the waste toner reservoir, a first agitator provided in the waste toner reservoir, to transport the waste toner therein in the depth direction, a rotary member provided in the inlet portion, including a rotary shaft extending in a width direction perpendicular to the depth direction, and a drive transmission unit provided outside the waste toner reservoir, to transmit a drive force from the rotary member provided in the inlet portion to the first agitator provided in the waste toner reservoir and to drive the first agitator in conjunction with rotation of the rotary member.01-19-2012
