An image forming apparatus includes: an image carrier configured to carry an image; a transfer unit configured to transfer the image to a medium; and a cleaner configured to remove deposits on a surface of the image carrier after passing through a position of the transfer unit, in which when a type of a medium to be used is a first medium, the cleaner improves an ability to remove the deposits from the image carrier as compared with a case where the medium to be used is a second medium having a lower transfer sensitivity than the first medium.

Image forming apparatus

An image forming apparatus includes a transfer unit, a container, and a calculator. The transfer unit transfers to at least one recording medium at least one toner image formed in accordance with image data without margins set along edges of the at least one recording medium. The container contains toner collected from the transfer unit. The calculator calculates an amount of the toner of parts of the at least one toner image outside the edges of the at least one recording medium. A time period during which the container is able to be used is calculated in accordance with an accumulated amount of the toner calculated by the calculator.

A cleaner includes first and second cleaning plates. The first cleaning plate includes a first free end and performs cleaning by causing the first free end to be in contact with an outer circumferential surface of a cylindrical second transfer rotating body including an elastic layer, so that the outer circumferential surface is elastically deformed. The second cleaning plate includes a second free end and performs cleaning by causing the second free end to be in contact with a portion of the outer circumferential surface downstream of, in a rotational direction of the second transfer rotating body, a position where the first free end is in contact with the outer circumferential surface and where the outer circumferential surface is elastically deformed due to the contact of the outer circumferential surface with the first free end so as to have a smallest surface curvature in the outer circumferential surface.

Cleaner and image forming apparatus

An image forming apparatus includes a transfer unit and a static eliminating unit. The transfer unit transfers a toner image formed on an image holding body to a recording medium. The static eliminating unit is disposed downstream of the transfer unit in a transport direction in which the recording medium is transported, stores electric charge while the recording medium is passing through a recording medium transfer region, and releases the electric charge when a leading edge of the recording medium enters the recording medium transfer region.

A fixing device includes a fixing roller that fixes a toner image to a recording medium; a cleaning roller that contacts the fixing roller and rotates, and cleans off toner adhered to a surface of the fixing roller; and a collecting roller that contacts the cleaning roller and rotates, and collects toner adhered to a surface of the cleaning roller, the collecting roller including an air passage section that extends through the collecting roller in an axial direction of the collecting roller and through which air passes.

Fixing device, collecting roller, and image forming apparatus

A fixing device includes a fixing member, a first roller, a second roller, a detector, and an adjustment unit. The fixing member fixes, on a recording medium, a toner image formed on the recording medium. The first roller performs cleaning of toner sticking to a surface of the fixing member. The second roller collects the toner sticking to a surface of the first roller. The detector detects a temperature of the second roller. The adjustment unit adjusts the temperature of the second roller on a basis of a result of detection performed by the detector.

Fixing device, image forming apparatus, and non-transitory computer readable medium

A blowing device includes a blower that blows air and an air duct including an inlet and an outlet. The air duct takes in the air through the inlet and guiding the air so that the air flows out through the outlet toward a corona discharge unit including a target component toward which the air is to be blown. The outlet of the air duct includes a through-portion in a non-overlapping region thereof, the non-overlapping region being a region of the outlet excluding an overlapping region of the outlet. The overlapping region corresponds to an interposed component of the corona discharge unit, the interposed component being located between the outlet and the target component at a position at which the interposed component overlaps the overlapping region.

Blowing device and image forming apparatus

A cleaning device includes a cleaning blade that contacts a surface of a member to be cleaned to remove a residue remaining on the surface of the member to be cleaned, and that includes multiple layers, wherein a leading end portion of the cleaning blade shifts in a separating direction from the surface of the member to be cleaned due to a difference in thermal expansion property among the multiple layers when temperature rises.

Cleaning device and image forming apparatus using the same

The present invention provides a cleaning device including a cleaning member that cleans a surface of a rotating cylindrical element to be cleaned, and whose length in a longitudinal direction is longer than a length of the maximum operating region of the element to be cleaned, a length of a contact part of the cleaning member at which the cleaning member contacts with the element to be cleaned being shorter than the length in the longitudinal direction of the cleaning member, and the contact part being moved in the longitudinal direction of the element to be cleaned.

Cleaning device, process cartridge and image formation apparatus

An image forming apparatus includes: an image carrier that rotates; and a charging member that is provided opposingly to the image carrier, and that charges a surface of the image carrier, wherein a discharge inhibitor that suppresses a discharge in an axial end portion is interposed in a portion where the charging member is opposed to the image carrier.
