摘要： An image forming apparatus includes an image carrier removably installed in the apparatus to carry an image; a transfer member contacting with the image carrier to transfer the image onto the transfer member or a recording medium; a contact and separation mechanism causing the transfer member to contact with or separate from the image carrier; and a removable unit removably installed in the apparatus from the same direction as an installation direction of the image carrier to be disposed proximal of the image carrier and the transfer member in the installation direction, and at least partially overlapping the image carrier and the transfer member as viewed in the installation direction. The removable unit interferes with the contact and separation mechanism and is prevented from being installed in the apparatus, when the transfer member is separated from the image carrier by the contact and separation mechanism.

摘要： 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 collection container for collecting and containing waste toner includes a leveling member, a detector, and at least one inlet. The leveling member levels the waste toner contained in the collection container. The detector detects an amount of the waste toner contained in the collection container. The leveling member levels the waste toner delivered to the collection container through the at least one inlet by conveying the waste toner simultaneously in a first direction toward the detector and a second direction opposite to the first direction, starting from an origination position corresponding to the at least one inlet.

摘要： 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.

摘要翻译： 当未使用润滑剂涂布单元时，润滑剂涂布单元的残留调色剂收集率X为50％。 收集率X通过X =（Ta-Tb）/ Ta×100获得，其中Ta是未与润滑剂施加单元接触的图像载体的区域上残留调色剂的每单位面积的重量， Tb是与润滑剂施加单元接触的图像载体的区域上的残留调色剂的每单位面积的重量。

摘要： 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.

摘要： A blade of a cleaning device includes two surfaces: an upstream side surface and a downstream side surface. The two surfaces adjoin each other with respect to a contact edge of the blade. The upstream side surface has a longer dimension in the direction orthogonal to the contact edge than that of the downstream side surface. A horizontal portion of a blade holder that restricts a warp in the blade is bonded on an opposed surface to the upstream side surface of the blade. The blade is held via the horizontal portion with a vertical portion of the blade holder supported by the main body of the cleaning device in a downstream of a normal line to a contact point on a photoconductor surface in contact with the contact edge, in the photoconductor-surface moving direction.

摘要： An image forming apparatus including an image bearing member, a charging member, and a measuring member. The image forming member is configured to bear an image. The charging member is configured to charge a surface of the image bearing member when a direct current bias voltage is added to at least an alternating bias voltage which is applied to the charging member, and has a frequency fc of the alternating bias voltage. The measuring member is configured to measure a potential of the surface of the image bearing member, and has a drive frequency fvsen. The relationship of the frequency fc and the drive frequency fvsen is expressed as fc≠fvsen×n and fc×n≠fvsen.
